Hey guys, so here's my newest dilemma, just picked up an 00, was told it has low compression in a few cylinders, and it's allowing exhaust into the coolant, and it's burning it for sure, saw some oil mixed in, pulled the dipstick doesn't look milky, and there is some milky residue under the oil fill cap- havnt drained out the oil to see what that looks like....engine starts, doesn't seem to be missing at all, and doesn't have any abnormal sounds...other than the loud as **** exhaust as someone yanked the cat off and left everything hanging lol. Has about 140,000 miles on it, has been sitting for like 6 years I guess, but I got it running within 30 mins of getting the hood open.
I picked up an engine today out of a 96- has about 230000ish miles and was told it ran when pulled, was too cheap to pass up...
So the question is do I swap in the 96, or do I swap the heads and do a bit of converting to avoid the higher milage and doing a complete swap? What's the concenseous here?
Jeep was free and it's CLEAN, it's ridiculous, engine was 100$... Just trying to decide where my money/time is better spent and wondering what others have done, or stuff to look at, consider ect...
Thanks in advance!

I don't know how much coolant made it into the oil, saw some oil in the coolant though, good thought though considering the time it's sat.
Still a big concern if I were to drain it and find minimal mixing?

pull the head and manifolds in one unit- cut more of the exhaust if you gotta to make it easy... cut pipe behind the upstream o2.
get eyes on the cylinder walls and pistons. wipe off and blow out the push rods- roll them on a flat.
get a look at the galley- tape a small long cone funnel to a vacuum like a little straw, and clear it out best you can...
then- pour deisel or kerosene through the galley to an open crank case into a deep pan, and see how clumpy it is. blow out the galley with air- clean it as good as you can.
suck (with funnel tool) all the crap off the lifters...
button it up with new head and gaskets, oil her up, fire her up.. run it for no more than ten minutes- then swap filter and oil... do this twice... run the exhaust out and away...
get a compression and a leak down test...
get some restore and some restore plus if you pass the leakdown. pull the 'stat out... follow the letter of the restore and restore+ instructions, to a T.... install new stat... flush with hose water no less than five times, including pulling bloack drain. use an airlift tool and identify if the cooling system is holding at least 25psi of vacuum indefinitely. use vacuum to pull 50/50 antifreeze straight from bottle, and draw another vacuum until it's full... install new cap if all checks out good.
run it for a few hours and change the oil/filter again.
see how it goes....
these engines are pretty tough- it may be that it has lots of life left.
you can use archoil 6100 in it and follow those instructions to the letter, and use archoil 9200 in every oil change... 6100 fills imperfections on hard parts and adheres like nobodies concern- 9200 is super slick and great for aging bearings.

Aka, probably worth the time to swap the head over? Lol.
That's a hell of a response though, with a few things I've never heard of, time to familiarize myself up.
also first time doing what I would consider "engine work", messed with almost everything else, even done a swap before, never cracked one open though, should be interesting.

Any other concerns, tricks tips ect for tossing in a 0630 out of a 96 in place of the 0331?
Havnt started yet as I'm dealing with a title hang up at the moment, but trying to get my ducks in a row before pulling the head on the donor.

Which head gasket and why- go!

I was thinking about just doing this kit as well, just because it's cheaper and has everything...dunno which head gasket is in it though.

Never knew there were that many options out there for this.
