Rebuilding/Cleaning up 350?
OK folks. I have an 80 CJ5 that had a 350 installed. I looked the casting number up and found out it is a 70-76 SBC. It has set up this past year due to the trans leak and basically it is a summer vehicle for me, wife,and the kids to ride around in.
My main problem is that I would really like to get into the engine and clean it up, of course fix what visibly needed fixing. Possibly, at least replace the gaskets and seals. I have been looking at a couple of threads getting into rebuilding there motors and people suggested taking it to machine shops and the whole nine yards.
I am completely ililterate when it comes to engines. Am I capable of anything? HAHA I do have some mechanics around, but really not looking into forking out a lot of money for someone to rebuild it. What I planned on doing tomorrow is getting it cranked up a,d running some seafoam thru it. Then, I do know that the rear seal needs to be replaced, so I can get that done in the next week or so.
What do you guys think I should do? I am not lookng for a suped up ride. I feel a 350 in a CJ5 is plenty enough already.

I would suggest finding someone who knows someone between friends and family and find a good Mechanic to help you out. It is pretty delacate work to rebuild an engine.
Id start with a compression test. If the engine is in good shape just do an standard tune up(plugs ,wires, PCV, oil, filters, rotor cap etc..) degrease and a light careful pressure spray, maybe get some good hi temp paints and paint the covers, etc... Got any pictures you could post.
Just my thoughts, good luck getting her fixed up!

Keep the oil and filter changed regularly, and with a lite load a 350 can go over 500k miles.
My advice would be change that rear seal(or the whole pan gasket set if you need to) and see how she runs. You may be in luck, if the engine internals are running OK, why borrow trouble?

I think you should give up on it and just give it away to someone.
Like me!
I'm a huge fan of the CJ's and one with a Chevy drive train makes me excited!
But seriously my advice is if it aint broke, don't fix it.

I will see about getting some pics up in the next day or so.
How can I do a compression test myself? Or can I? I do plan on replacing the rear seal, and I guess it probably wouldn't hurt to replace the pan gaske also. And as far as the tune up, I can handle that myself. All that stuff goes in the dash right? HAHA j/k
Thanks for the replies.

Also. Is changing the oil pan gasket like changing the trans pan gasket?

On the oil pan , pretty much same procedure in my opinion, just a little harder to get to in some cases.

OK guys. I got some pics put up so you can see what I am working with. Keep in mind that it has been sitting up for the better part of a year.
Any comments recommendations are appreciated. One of my main concerns also is in the 4th pic. That is the passengers side cover. It has a breather? hole in it. I remember some time ago pulling what looked to be a rubber ring out of it only because it was corroded and looked like it was fixing to fall into the cover. What is this for? Should I just put a grommet in there, or should something else go there?
thanks

It was the fresh air intake for the PCV system. Once upon a time it had a hose in it that connected to the original air filter housing. You can get a PVC filter from the auto parts store, right now it is pulling dust/ dirt into the engine. You will probably need to get the grommet though, it is available at the dealer and is the same in every 350 up until 1995.
