Save everything you've got room to store.

True story on that.... there are a few parts off the spare XJ I was parting out that I was kicking myself for selling/scrapping after the fact.

Much more scarce on an MJ

I don't plan on rebuilding the engine, just replacing the gaskets. However about the trans; the guy who bought the jeep from the owner told me that the owner insisted the clutch was in dire need of replacing. But when he drove the jeep home, he said it drove just fine. And when we took the trans out, the clutch still have a lot of material on it.

Makes me think there may be something else wrong with the trans that could mimic clutch issues? Should I rebuild the trans?

And is there any good recommendations for flywheels and clutch kits?

Maybe out of adjustment? I remember when I borrowed that dark green XJ to drive around, the lady said the clutch was just replaced (AX15) but you could put your foot to the floor sometimes and it would still grind going into the next gear. Then after driving it for a bit, you almost couldn't get it to go into first, even if you were trying to slide it in as you were rolling to a stop.

I thought it was the clutch fluid, but I can't remember if I ever even checked it or not.

Lack of lube in the gearbox can mimic a clutch that doesn't release. But it's have to be almost dry

Could also be air in the master/slave cylinders. Had an s-dime one time that had air in the system and caused it to have all kind of funky clutch.

No way man, your transmission's fine. You need to replace the CPS with an Airtex unit

I would replace them, they are cheap enough, and it's piece of mind.

So today I went and got my lathe out of storage & brought it back home, along with other stuff from storage. Had a bit of time to re organize the garage too. Yay.

I decided to look at the numbers on the MJ block. Get this... it's a '96 block with a 7120 head. Came out of the 91 MJ with 129k miles on it. Makes me wonder what happened to the original engine.

Peered inside the oil fill hole and it look clean inside.

Oh yea. I took the engine stand out. Need to convert it from 3 wheel to 4 wheel before I put the engine on it for gasket overhaul.

As usual the 88 mj ran like a champ.
