Questions on buying used 304?

I have located a CJ 7 with a 304 3 speed tranny and DANA 20 transfer case. The owner was not sure of the exact year. He bought the Jeep about a year ago and he bought it wrecked. He told me it had hit a gas main and broke the frame on both sides right in front of the tub. He said the grill hood and finders are all in good shape. The Jeep has not ran since he has owned it and he has sold off several parts. The back axle, front hubs, and the interior. All of which I do not need or want. My question is that I am trying to think of anything I can do to check the engine while it is sitting there. All I hope to gain out of this is a good engine to rebuild and nothing more. I known how to manual turn the engine over and am just looking for some more suggestions or things to check. By the way I can buy what is left of the Jeep for $175.00.

If you are going to rebuild it you don't really have to worry besides a cracked block or really screwed up heads. I'd look for the block to be covered in oil, that may be a clue that something major is up but I wouldn't look for much or, you could try a compression test, that would tell you if the rings are bad but you will probably repace those.

Well like Jeeper said.. you can just do a good visual check for cracks first.. the compression test might help alittle, but that only shows you whats wrong and if your getting it rebuilt - you really dont care [img]/wwwthreads_images/icons/smile.gif[/img]. Check for leaking oil,fluids,ect.. Pull Valve Covers off and see if most things seem in order. Pull plugs and get a big ratchet and turn the crank on the engine and see how well it turns.. Maybe even just hook the starter up to a battery and turn it over? What else am I missing?

The left over parts are worth the $175 and then some. If the title is available I would snatch it up.

The core charge for a motor at most rebuilders is around $300-$400. If you do not have a good block to exchange, they will charge you the core.

Good Luck!

You can also check the coolant and see how that looks and the engine oil. If theres water in the oil or oil in the coolant there could be a cracked block or a bad gasket.
