Rebuild manual/guide for 2.8/3.1/3.4?
Hey all!
Would anyone be so kind as to have a PDF or something similar of a manual which describes a typical engine rebuild of a 2.8/3.1/3.4 ?
Or perhaps where to get one?
Thanks for any help guys!

But that wasn't the question.
This isn't an Engine Swap topic.
Brace yourself for a moving experience...

Wow, what a moving experience.
I kinda thought I was in the wrong place, was a 50/50 chance and I chose wrong :P
Anyhow, this is why I am working on the engine. Because it is easy to work on and there is no real time constraint. The car has been dead for 3 years now, so if I kill anything, it will make little difference. I got the used complete 89 engine with the cracked block for 35$.
This kinda links with my post elsewhere regarding 86-89 block differences.
I am kinda in it for the learning experience. Hence the quest for a manual or guide of some kind.
I do have people around who are able to help me should problems arise. I also have access to pretty much any tool I would need to do the job.
I would go out and purchase a rebuild guide, I am pretty sure I have seen tbem. However being broke at the moment has caused me to become cheap. At least for now.
I like to research stuff alot before I spend any real money on it, so at least I am reasonably sure I am not throwing away my money.
Now that I have made your eyes sag from all this typing....
At least you know the story behind my little project.

IF you are really set on doing it cheap,
Go get new rings & bearings & oil pump.
About $100 or so
Pull the pistons & clean them & make sure the piston ring area is also clean, too.
Swap stuff back & forth.
IF got any money left over go get a cylinder glaze honer and get to work.
BUT for the effort, it would be wiser to find a used running engine and stick that in. Even up there, they can be found. Cheap. Scrap pile the old stuff ya got for cheap. That's really wiser.
The odds of making the two piles work well for your effort is kinda low. Really try to find a used running engine & put your effort there, in a sanitary swap.

Thanks for the suggestion.
I happen to have access to a honing tool. I was pretty much figuring on doing exactly what you said to do in regards to cleaning, new rings berings, etc.
I do understand that it would make more financial sence to simply get a used running engine, toss it in then off I go.
It is far more logical as well. I completely see your point.
In fact, if I was bound and determined to get the car running, and there was a limit to the time I have to get it to that point, I would definately scrap the stuff I have now, and follow your good advice.
But the main reason I am even doing this is to get some experience with engine work. Its to broaden my understanding of engine workings and see what its like to do a simple rebuild.
It gets me outside and keeps me out of trouble.
The more I look at the engines I have now, the more it seems to me that the process itself is going to be quite simple once the parts I need are in place.
Even still, I like to have some documentation on the task so I can do things right. There is no sence learning wrong.. right?
I hope this makes some sence here. Its still early for me, and I have had very little coffee.

Actually, I would go the route demicon is suggesting.
Why?
How pissed would you be, to have spent a weekend swapping motors, only to have a spun rod 2 months down the road?
Sorry, but EVERY engine I've EVER pulled has been pulled apart, and mains/rods/rings checked. I usually start the entire pulling routing, with a compression check - just to see how worn the motor is, and where I need to work on it, first.

Demicon, if you have ANY mechanical aptitude, you will find the actual guts of the motor, EXTREMELY simple. If you have any questions, just ask us

Doward, yeah I do have decent mechanical abilities.
Like I said it really does not look too hard.
I will be sure to come here for any snags I run into.
Thanks again
