REBUILDING THE ENGINE IN A 2004 SUBARU OUTBACK - TECHNICIAN'S GUIDE - Part Two

Well it's done; the engine rebuild. I didn't mess with the pistons, they were fine from what I saw. Yesterday I worked from 10 AM to 7 PM.

I began by uncovering the timing belt. Sorry no new pictures, to busy working;  but seen here in the following picture you need to remove the harmonic balancer, #1 here. Ah, there's a bit more involved; the harmonic has the timing grove on it. You need to rotate the engine clock-wise until the grove lines up with top-dead-center.There are two engine rotations for T-D-C. One rotation would put cylinder #1 at low exhaust. That is not what you want. The #1 cylinder has to be at the max compression stroke, that's the other rotation. 180 degrees apart. The book suggests a cylinder pressure gauge. I don't have one. So I rely on an older trick. I find a dowel, and seat it into cylinder #1. I mark the dowel, rotate the engine to T-D-C. When the dowel is farthest out, that's the max compression. Leave the harminic pointed at T-D-C on the gauge in place on the plastic cover.

You've done that - or I have. I use a permanent white marker to document points of alignment. White dots everywhere. An excellent decision. Now, using an electric impact gun, and an old belt to stabilize the harmonic, I run the impact gun counter-clockwise on the bolt in the center to loosen it.

I then remove the many bolts holding the plastic cover in place, and moving a few odds and ends out of the way.

I find replacing bolts loosely in places the aren't in the way, and using separate cans for bolts I remove make things easier.

I recommend having a stool like a milk-crate to sit on, and a table for your tools.

With the plastic cover removed the timing belt, water-pump and many bearings and gear are revealed. Again, using a white permanent marker I make alignment marks, at least two. I do this to the crankshaft gear (that was connected to the harmonic balancer) to denote T-D-C, as well as the two opposite camshaft gears, marking their locations prior to removing the timing belt. Failure to do this will create a mess. The timing belt comes off easy, but then the camshafts relax a half to a full inch. To be able to install the new belt everything must line up. But that comes last.

Subaru's have a interference engine. Simply put it's different with a head on each side, rather than one on top, and if the timing belt breaks it doesn't destroy the engine.

Removing the first head, closest to the 1 in the image above wasn't real difficult. Loosening the 6 head-bolts was the challenge. Then I partially unbolted the intake manifold, and removed the head. The book says you must remove the camshaft and lifters also - a major pain in the ass. I saw no need to do that as the head-bolts are right there, and it worked out well.

With the head removed I could examine and admire it. I wasn't going to have the heads resurfaced - which is recommended, rather I carefully used a sharp and stiff scrapper to try and get as much remaining gasket free, using very fine steel wool in a few places. The less the better.

The gasket(s) that came off were ruined, and I could tell it wasn't from removing them. Fortunately there was no indication of anti-freeze in the pistons, which you can see with the head removed. The replacement head-gaskets I bought are Fel-Pro Perma-Torque. They are two steel sheets with a special surface. The old gasket was a single sheet of steel with a gasket type finish and that is what had failed.

Finally able to insert new gaskets for both the head and the head-intake manifold, and it's down to torquing 6 new bolts. Now the torquing sequence is new. I'm old school where you torque to a specific ft-pounds in a special pattern. But this Subaru, you use a torque wrench to tighten to an initial torque, then back off 180 degrees, then another 180 degrees, the torque two center bolts to this minor level, and the other 4 to half that. The use a angle torque tool (something completely new to me) to continue torquing first 80 - 90 degrees, then finish with an additional 80 - 90 degrees.

Wow, hope the first head I worked on is okay... it was a learning experience. I did much better with the other head.

Oil pan gasket now replaced also... and thanks to my fore-thought the timing belt is back on and if not for those position dots, the timing belt would have been a major head-ache. New water-pump installed, cover back on, harmonic reconnected - torqued using the impact gun in clock-wise. Ready to swap between engine stand to engine hoist, install new clutch, and reattach engine to transmission.

Oh yeah, and replace the drive-shaft.

REBUILDING THE ENGINE IN A 2004 SUBARU OUTBACK - A TECHNICIAN'S GUIDE - Part One

A neighbor gave me the car for next to nothing. It had 212,000 miles on it. It needed engine work. He bought one just like it, same year with half the mileage... guess he likes the car - I know I sure do and I drove it 150 a day to work for a month before this week.

The car has next to no rust and is in fine shape other than the routine work needing to be done. The list is pretty long.

Replace both head-gaskets; replace the timing belt, the water-pump, and oil pump seals. Replace the clutch, maybe the front drive shafts - one on hand - one confirmed bad.

A brief history about me. My father was a Navy mechanic... used to work on the Corsair fighter planes. After I was born he wanted to open his own auto garage. It fell through. Money.

Somehow, instead he became a sales-manager for big industry. But being mechanical was in my blood... beginning around age 19 I began to do all my own car work. That was around 1973.

The repairs seem much more frequent back then, Cars today seem more reliable than back then.

Around 1984 I got an apprentice job working for Volvo as a mechanic. We were called technicians. I stayed there for awhile until I finished what I needed and moved on, to a specialty Saab/Volvo repair shop. I loved those cars back then, owned several Saab 99's, over those years. But they had problems and so did the shop. After about a year and a half I got laid off... for a couple months until I met the boss from the Volvo place and he said he was now the service manager at a dealership, and if I wanted a job I had one. I took it.

The goal is to assure you I know cars. I've been working on them for over 40 years.

Thus the prospect of pulling the engine out of my new 2004 Subaru Outback was simply a challenge. Like a - it's been 30 years maybe since I've done something of this complexity, Am I serious or insane???

Too late... half the jobs finished. I took the week off to pull the engine and replace the stuff it needs. Fortunately I had a garage to work in as the temps were in the 50's and none too supportive. Sunday and Monday was a matter of draining the radiator - a plastic bleed screw on the bottom right of the radiator. Both radiator hose clamps were rusted beyond reuse; the upper I simply wrenched until it fell apart. The bottom hose was worse... I had to cut that one. I''ll deal with replacing them later.

I have to say all the wiring is very straight forward, color and shape coded, so about the worst that might happen is forgetting to plug something back in. Intuitive type car to work on; but that's not to say it's for beginners.  This is what's called an interference engine by Subaru:

It's my engine on an engine stand in the garage. It was no small feat getting it to that pristine location.

What they don't tell you in the manuals or online:

1) The only thing holding the engine down are two engine mounts - they are generally easy to remove found outwards on either side of the underside of the vehicle. There is nothing holding the engine down directly center underneath. The rest of what's holding the engine connected to the trans-axle are 4 threaded studs, and I believe 4 bolts.

At the moment of the photo it was resting lightly on a stack of heavy cardboard, with a slight life by the hoist. At this point the clutch has to come off. And easy job with an electric impact gun.. From here it's time to mount to the engine stand.

I was certainly confused by how an engine stand worked, until today. They are sturdy stands with 4 swivels that both allow you to attach 4 bolts to the bell-housing (shown above) as well as have them firmly fixed to the stand - and this is accomplished as the mounts are able to swivel and slide.

But...

2) I neglected the most important part. The how of how it got to be so beautiful on that engine stand.

The idea is to disconnect anything attached to the engine. That's a lot of work. Then you need to disconnect the air conditioning and power steering pump. Disconnect the exhaust manifolds and remove all the nuts and bolts holding the engine to the bell-housing and transmission.

Now attach the engine hoist, and - forgot, only because I found out about this later - a You-Tube Vidio on problems separating the engine. Maybe it will help others, it got me motivated at least:

https://www.youtube.com/watch?v=hp7JtBfv8QU

The problem was this, despite every effort the engine would not part from the bell-housing. A friend showed up just then; a burly friend, a carpenter. He was happy to help, and like a true Viking he made that engine rock as I raised and lowered it. Not a crack emerged from all the rocking and shaking! Well, except he suddenly said there might be a crack here, on the right side... go get the metal 1" gasket scrapper. I reminded him prying at the seam was discouraged. He was like do you have a better idea?

I got the scraper, and he proceeded to hammer away on one side then move to the other side, until the gap was wide enough for a bigger wedge, and the engine finally detached.

In the photo above I'm showing where my friend first had to wedge the gasket scrapper ....

So all is good, right? Well it seems the manual doesn't say anything about moving the vehicle out of the garage to park it while doing repairs on the engine. Upon backing the car up - pushing the car out of the garage (I had left it in neutral, which was smart), the transmission rotated enough that the inner bearings fell out of the right-hand drive shaft:

The boot had split already and fortunately I had already bought a replacement drive shaft, planning ahead; just didn't think I'd have to replace it this week! I do now.

The picture above is the transmission/bell-housing, still in the car. That's the throw-out bearing and clutch arm in the center that will need replacing.

Now comes the fun part... rebuilding the engine.

REEFER WARNINGS: BRAIN ABNORMALITIES, DEATHS AND DANGERS ATTRIBUTED TO LEGAL MARIJUANA

Edited to clarify the intent, add essential content, April 29, 2014, 8:45 EST

I was going to write an educational, upbeat article about car repair or whether to upgrade that old computer of yours with the now unsupported Window's XP operating system on it. But I can't in good conscience ignore the events surrounding this year's 420 celebrations and media reports of deaths by marijuana and studies suggesting that marijuana causes brain abnormalities. With a government run amok as we have, with multiple infringements on human rights and privacy, along with deceit, it's time for "Truth And Consequences".

Law enforcement and criminologists have long sought a way to positively identify psychopaths and sociopaths, without much success. Perhaps that will change as scientists discover more about how to read our minds and see our thoughts. It's a noble, righteous cause. A goal to make the world a safer place, which brings us closer to being civilized.

However such studies and research are poorly funded. The government teeters on bankruptcy. Our infrastructure is in serious need of repair and upgrades. Our schools are often in crisis, burdened with Bush Era "No Child Left Behind" mandates; without much funding. The reason for these problems is simple. Since 1971 our federal government has been waging a war; a war against millions of our own citizens. It's called the War on Drugs, enacted by President Richard Nixon and he created the DEA as the overseers. He orchestrated the Scheduled Drug policy, making sure marijuana was Schedule One, and making marijuana the Number One Criminal Offense in this country. Trillions of tax-payer dollars have been spent on this war.

A war it appears that may soon be lost, if it wasn't when it started? But is there hope???  

A study released a week prior to celebrations of marijuana called "420" was conducted by the Northwestern University Feinberg School of Medicine appearing in multiple news-outlets and will appear in the Journal of Neuroscience. The results of the study suggest, or rather attempt to prove that marijuana causes abnormalities to two parts of the brain, parts that affect memory, learning, good judgement, and motivation. The following is a quote and a link to the news article as reported by Fox News, April 15, 2014, 5 days prior to 420:

"For the first time, researchers at Northwestern University have analyzed the relationship between casual use of marijuana and brain changes – and found that young adults who used cannabis just once or twice a week showed significant abnormalities in two important brain structures".

For the first time...

I don't think so... the federal government has been conducting research on the very same thing since before 1971.

For the first time... maybe this study suggests the human brain is not as static (unchanging) as has been assumed. At the very least if this study has any redeeming qualities, it's that what we take in can cause a change to our brains... not just cannabis, but other things like alcohol, tobacco, coffee, tea or milk, to name but a few substances.

An article on Alternet does an excellent job analyzing the study: "Why the Media's Fearmongering on Marijuana Effects on the Brain Is Faulty."

More than likely the study was flawed or simply a joke, like this article about 37 people dying from marijuana in Colorado on the "first day it was legalized":

The Daily Currant, Jan 02, 2014"Marijuana Overdoses Kill 37 in Colorado On First Day of Legalization."


Debunked on FakeNews.Com

That's not to say there haven't been deaths associated with marijuana use this year, as there have been allegedly two such deaths.

One was a man apparently had too much of a marijuana cookie too soon. He didn't take the recommended dose of 1/6th of a cookie and wait 45 minutes to an hour. He became impatient after so many minutes and ate the whole cookie. He went mad and jumped out a window to his death.

The other was death involved a spouse, Whose husband had ingested a marijuana infused edible,  and went crazy several hours later, killing his wife who was on the phone with 911.

You can read about them here:

ByCrimesider StaffAP April 18, 2014, 11:04 AM "Two Denver deaths tied to recreational marijuana use..."


One might want to do some research at the very last place we'd consider looking, the CDC. Fact is, "there are approximately 88,000 deaths attributable to excessive alcohol use each year in the United States".

So how much is too much? Where does the mudslinging end? When do we get real and realize Nixon's "War On Drugs" was wrong?

TODAY:

21 states have laws permitting medical use of marijuana, 18 states have decriminalized marijuana to a fine for certain amounts, 2 states allow both medical and recreational use and one city in Maine has outright legalized possession of two ounces.

I began this post with the observation we as a society are suffering. The great benefit of the War on Drugs is our penal system is bursting at the seams. I'm not proud of being a part of that while paying my taxes. Let's be frank, legalizing marijuana is bad for law enforcement. It is the central hub of the wheel of drugs, for money, per popular misconception.

I'm referring to murders, kidnappings, armed robberies, rape, assaults...and why these aren't as important anymore.

Well the following article may help explain that mindset:

It turns out "science" takes third after religion and politics.

Fox News: "AP-GfK Poll: Most agree with scientists on smoking, fewer buy Big Bang, evolution or warming". WASHINGTON –  "Few Americans question that smoking causes cancer. But they express bigger doubts as concepts that scientists consider to be truths get further from our own experiences and the present time, an Associated Press-GfK poll found."

President Obama promised an administration that placed science first. It's questionable how successful he's been. Part of the answer might reside in what we take to believe is truth.

Imagine you've never had a cup of coffee, or your first experience drinking a double espresso recommended by a friend? Or you're a good girl, over 21 and you've never been to a bar. Your friends take you out. You have a good time - you get drunk and ...

The science doesn't matter. Now imagine you're 19 and very anti-drug and your best friend offers you some marijuana? Everything you've always been told via politics and religion is it will make me mad and insane and it is illegal! But I try it anyways, fearful and cynical...and I discover it not only feels very good to me, but it has a most profound and extraordinarily beneficial effect on my life and my future. It changed my life for the better, without a doubt!. .

Obviously I care about science. You don't have to use cannabis to be aware the science is out there and that it's at least as safe as alcohol, if not safer. Life is a risk period. Why are we prohibited to take a risk with far fewer dangers than what is already out there? I took a risk in 1973 using cannabis and it changed my life for the better a hundred fold. It also made me a criminal. That's politics. Wrong politics. It's time for a change and it's time to accept the flower children, before we all die off.

MENTAL ILLNESS IN AMERICA, GUN CONTROL AND THE MARIJUANA MYTHOS...

According to the National Institute of Health - NIH, over one quarter of the American population has a mental illness of some kind. LINK: NIH -MENTAL ILLNESS IN AMERICA.

Often, mental health issues are linked with substance abuse issues. Although one might expect that illegal drugs would be most closely tracked and publicized, the truth is strange as the NIH and other foundations actually compares mental illness rates to alcohol, tobacco, and illegal or legit drug use.

The KIM FOUNDATION is another useful website that looks at the actual statistics for mental health and categorizes the conditions.

My feeling is the number of Americans with a mental health illness is double the number suggested. Too many people go through life ignoring the obvious. Too many families are dysfunctional. There is very little out there educationally with regards to being a family, being parents, being the child.

I'm opposed to government intervention into the life of a family, however, going blindly into being a family seems somewhat antiquated to me. Where are the family colleges? Perhaps I should start one.

We do have laws... we have a child protective services division in most states... the trouble is, too many mistakes happen. The criteria for intervention is either outdated or insufficient. We take children away from parents when it's discovered one or both parents use, or did use marijuana. When one or both parents are arrested for marijuana. Contrast that to use of alcohol or tobacco, child abuse or child neglect.... often hard to prove or make a case for.

Having a beer is like smoking a bowl of pot. It's a question and the answer is difficult to ascertain. Why? Because they are different substances. A truck is different than a car, a trip to China is different than a trip to the Grand Canyon in AZ. We live in a world of diversity. Also a dying world.

In the near 60 years I've been alive on the planet in the United States I have witnessed a surreal idyllic world growing up as a child to a world that is endangered by consequences of what humankind has created in the past 200 years. Global warming, destruction of natural habitat, disregard for nature. As a child the world had none of these destructive concerns...  we only worried over the "Cold War" with the Soviet Union.

***

It's the year 2014... 

Marijuana is still a Schedule One drug at a federal level, however two states along with Portland ME have legalized recreational use of cannabis, and 21 other states allow medical use for cannabis.

You can't however own a gun, if, you're a marijuana user, whether state legal or not. You can own a gun no-matter how much alcohol you consume, and tobacco use is not an issue. 

Although many people in a state where marijuana is legal possess a gun, technically, the federal ATF controls the right to ownership, and since marijuana is a Schedule One drug, it's illegal to possess a gun. 

There are also those on the Right who feel anyone with a mental health condition should be denied access or right to possessing a firearm. As I previously pointed out, that's at least a quarter of society, if not more. I say if not more as I personally know about individuals with mental health issues completely off the grid that own guns. They stay off the grid to secure their 2nd amendment rights. 

They may suffer from any of several mental illnesses as previously discussed. To say outright they shouldn't possess a firearm is ludicrous. How often is it that the non-substance abuse, non-drug anything individual is the one to create chaos? 

It's convenient to be able to say those 24% + person's cannot possess a gun. But of those 24% who seeks therapy and assistance in coping with life? The majority I'd say as that is probably where the statistics come from  and not the actual percentage, which as I suggested is more like 50 - 60% of the population. If so, two scenarios... prevent a marijuana user from possessing a gun, a useless proposal, but there goes 25% of the population, and then those with a mental health disorder, I say 50%... requires mental health evaluations to own a gun. 

But is that realistic? No, it's not.

Marijuana use does not contribute to gun violence and as such should be removed from restrictions. Alcohol use does lend to gun violence and should therefore be considered. 

Of those people I know who claim they are free from mental health issues, I can only say good luck. I can also say among those who seek mental health treatment the evidence of gun violence will decrease. Those who refuse treatment are most prone to commit gun violence, something generally ignored in society.

It seems rather twisted that those we respect that show no evidence of a mental health issue more often than the reverse become a threat to society. But it is true. 

As long as we convince ourselves as a society that only "mentally sick" people need to seek help, we will be bound by a syndrome that essentially says if you don't admit it it's not true. 

To clarify:

Marijuana is not a prerequisite to violent behavior.

20 - 26% of the population are considered to be suffering a mental health illness.

The federal government wants to keep guns from those with mental health issues. 

The number is likely higher, more like 60%. 

There's a difference between those who seek treatment and those who don't.

Prohibiting gun ownership among those with a mental illness, something as simple as general depression, anxiety, ptsd or users of marijuana is not practical, let alone Constitutional. It is not practical as it doesn't take into account the whole story. Those who seek help and those who don't.

Your average serial killer or violent offender is not likely to have sought therapy! There are exceptions... but the majority don't seek assistance. The majority don't use marijuana.

The majority of violent offenders don't seek therapy and don't use marijuana.

Still it's fun to believe the majority of violent persons are in prison, under psychiatric observation, or use marijuana daily.   It simplifies who we should avoid. It simplifies drug testing in the work-place where marijuana is the drug most often in flagged.

But it does nothing to make America safer.  To do that we need to revisit science. But to revisit science means changing the way we do things, and what we have been led to believe is true.
