New to me 2000 XJ.

So my dad got this XJ last year and hasn't touched it since, idles like a champ, overheats and has water in the oil (im guessing due to the 0331 head cracking). so i'm going to check it out this weekend.

otherwise i'm swapping the BB/moabs off my 98 and selling it.

this 2000 is much cleaner.

Plans within the next 6 months-year. ofcourse fix the head.

-RCx 4.5" lift
-sye/ds
-some sort of roof rack
-jcr bumpers
-265/75/16 when the mtr's wear
-tint
-some sort of stereo setup, nothing huge, just clean w. a lil bass
-seat covers or leather seat swap
-exhuast
-anything maintinence wise i see needs done. overall its clean as hell



afternoon of work and got the front BB swapped over. smashed the living hell out of my pinky and called it a day on the mechanical work and did a little cleaning on it

Wow, that's way clean! Good luck!

I've got the same (2000 sport moabs) good luck with that head

Thanks guys. Mind posting a pic cnj?

so had a helluva day. went to the picknpull to get a 0630 casting head (98-99 xj's that aren't suppossed to be nearly prone to cracking, etc) mines a 2000 with the 0331 casting that is notorious for cracking.

anyways spend some time with tcoggins pulling the accessories out of the way on this 98 and getting the bolts loose, pulled the valve cover off, everything looked pretty good there so i figure what the hell we will try it out. after a trip back to my house to get a 1/2" break bar and to advance to get a 12pt 13mm deep socket, we managed to muscle the ridiculously tight head bolts off.

after fighting with the intake manifold for a while we got the head off, turned it over and a couple of the valves looked a little funny. so he was asking me about where the heads crack on the 0331 casting (b/t 3 and 4 combustion chambers) as i was grabbing the pushrods, etc.


at that time we noticed that there was effing port to wall crack b/t 3 & 4 on this 0630 casting head. needless to say i was slightly irritated, picked the thing up and threw it back on top of the motor and went to the house.

You must of found one that had seriously overheated since as you identified; the 0630 heads rarely have issues....
While going to the JY is certainly cheaper; most times you still need to have the head cleaned, magnifluxed, seat and valve job with new springs...
Almost sounds cheaper to buy one of the replacement heads for the 0331; which would be just a plug and play with a warranty....

:twak:That would be the proper way to do it. I bought a new 0331 head (new improved casting) and new head bolts and gasket, no issue's since.Anyways you dont have to cobble up a half-assed bracket to hold the coil packs and the ports are the right size.
