i have a 01 grand 2wd with 4.0 engine has a tick, pulled the engine out and grabbed one out of a 00 cherokee 4wd and the engine mounts wouldnt swap. was told i can take the frame mounts out of the cherokee and put them in the grand and then the engine would bolt up. or would it be better to just rebuild the 01 engine and use the 2000 head since the head is better on the 2000 model

If you dont mind me asking, why did you pull it for a "tick"?

SUBLEVEL88

well i didnt want to be driving it to work and the motor go out plus they had to get it hot and it was in the bottom end of the engine. the jeep is in perfect shape after rebuilding the engine i wont even have 1300 in everything

I wouldn't have pulled it for a tick. Jeeps in general have a slight tick due to an oiling part......... not sure what it's called but you can put your finger on it and feel the tick. It's totally common and not a bad thing.

Bottom end is a different story, makes sense.

Yea, the valves, but thats top end.


I say just swap if the donor engine runs fine

my engine mounts will not bolt up to the cherokee block. can i use cherokee engine and frame mounts in a grand cherokee

Diesel

Yes, it may need a little fab skill but its not difficult.

The blocks are the same between the two, I don't see how the engine would not just slide into place like the original. Could you show us some pics of both engines?

04+ has the better 0331 cyl head. Your replacement is identical to the original.

The WJ blocks are cast different, an XJ engine does not work.

You need another WJ engine or a late TJ engine to swap in.

The "tick" alot of WJ owners talk about usually are the evap cannister, or a broken piston skirt.

rizmonkey

Not the valves........... it's a smaller little square block near the side of the engine. It ticks like a heartbeat.......... you can put your finger on it and feel it.

I know what valves are.

thank you overland im just going to rebuild the engine that came with it.

Drain the oil... any metal particles?



That box would be the evap cannister..

Bustedback

I did not know there were two different castings between the XJ and WJ, why would Chrysler do that?

SUBLEVEL88

i didnt know either i bought the jeep thinking that i would just have to change the engine mounts and i would be driving it this weekend but with my luck they would not swap and i dont want to halfway do the job when i can do it right for 300 for a egine kit

SUBLEVEL88

drain the oil no metal shavings , dropped the oil pan and #2 piston is cracked. 4.0 is a great engine not sure why i was getting a tic and not a hard knock lol
