what now
My son has a 1999 cherokee 4.0 with a locked up motor, so what direction would you go re-man, new, salvage yard, rebuild the old one?
looking at re-man long blocks but dont know who to trust
used seem high around here $1200.00 average at salvages
I could rebuild it myself but dont know why its locked up yet could be junk
thanks

Has anyone seen a 4.0 engine lockup without warning?
its my sons 1999 cherokee sport 4.0 auto 4x4, I wasnt there when it happened my son said he got on the hwy went about 4 miles it bogged down heard some noises (clanking?) he could not tell me what kind of noise it was making, when i got it towed to my shop it had oil and coolant, coolant looked like it might have a trace of oil in it, i tried to crank it and the starter was hitting hard but nothing turning over, so removed the serpinting belt and still locked, pulled the plugs all looked normal untill #6 came out tip is bent and porcelin missing & looked like something had rubbed on the side of the crown lightley, I was thinking it had hydostatic lock but its still frozen, help guys.
sorry for such a long post

I'm not concerned with why exactly why its locked up i'll do that later after i get him back on the road, i'm just mostly wanting to know who to trust in the re-man & or used industry, rebuilding the engine would be logical But that would take longer than a used or re-man, Ive noticed on re-mans they want the motor to turn 360 deg to call the core good
thanks

$1200 is kinda pricey, you can get a re-man for a little more & better warrantee.
You need to see why the motor will not rotate 360 & go from there, (i e remove the blockage so you can use the block for a core) rebuild or re-man.

yea i'll make sure it rotates before i use it as a core for sure, im ruling out the rebuilt just from a time factor, ive found a couple of used motors (this would give me a spare motor) with under 60,000 miles, my son loves his cherokee, so hell drive it a least untill he's out of college 21/2 years, and i agree if a re-mans only 400.00 more id rather do that but who makes a good one?

Myself, I wouldn't hesitate to check the local wrecking yard. You never know if you might get lucky, or really lucky! My guy has a 30 day warranty I think. Pretty sure you can go all the way from 91 to 99, and even back to 87. Safe bet you would keep the manifolds from 97 to 99. Heck, you might even be able to go 00-01, if your head will swap.
