Bought a 4.0L Craigslist engine for $250. Supposedly out of a 1995 Cherokee with 150K miles, but who knows.
Will be for a 2.5L to 4.0L swap in my 1995 YJ. I'm considering three options:
1) Full rebuild ($$$)
2) Head job, cleanup and external accessory replacements ($$)
3) Minimal cleanup, etc, and swap it in. ($)
If the engine is in good shape, I'd like to save some money, and NOT do the full rebuild. But I don't want to get the engine in, and then immediately pull it out for a spun bearing, cracked head or something.
Is there anything I can do to an engine on a hoist to figure out its condition? Ideas? Suggestions?
