I just picked up an 01 Cherokee with 181k off of CL for 300. I knew it had some problems. I've installed a new battery, starter and I got it fired up. Horrible noise is coming from Cyl 5,6. It appears to have a head gasket problem also. I added a link to the video of it running to see if anyone has ever come across this same problem.

Pull the oil pan and see if there are any goodies in it. (not my pic)

kclcpa

that one is done

Sounds bad and it looks like your oil has gone all nesquik which likely means a bad head gasket among your other problems. That motor sounds like it's toast.

Yea I ran out of daylight today. I will be pulling the pan tomorrow and getting it situated in my garage for the engine tear down. Any recommendations on rebuild kits?

Radi

Depends on which parts you want in the kit. Some have timing gears/chain, others don't include Pistons. Get a gasket kit (Victor Reinz) and probably just mix and match from there.

I have done some research and seen some people only changed the broken piston. This is just going to be my vehicle to and from work. I'm not going to wheel it. I might lift it down the road. I plan on doing new pistons all new bearings new timing set, water pump, alternator, oil pump and a new radiator. I'm going to send the block and head to the machine shop to have them checked.

Radi

I have mixed feelings on rebuilding a block that's marinaded in antifreeze, unless you check/replace the cam bearings too. Particularly with '00 and '01 which seem to develop low oil pressure problems somewhat easily.
What did it have for oil pressure, hot idle, before you started dismantling it?

Zackqb2

It was 40 PSI at idle cold. I didn't let the engine run for longer than 3 mins. The jeep has been setting since Oct when the problem happened.

Zackqb2

Well I haven't really found out the cause of the noise in the engine. I have just been working non stop. I was attempting to take the engine only out and 1 of the external Torx bolts stripped the head off. So I removed the engine trans and tcase.

Radi

That's the universally accepted hand signal for "the last damned bolt stripped".

If you have not replaced the cam bearings, bored the cylinders if needed, line bored the cam and mains, and surfaced the top, you have not rebuilt the engine, you've just swapped a few parts.

The cost of doing those things is trivial once you are that far. It makes no sense at all to not do them.

I agree with Blue.
Do it all.

Zackqb2

Motor and trans are separated. I will be putting it on a stand tomorrow.

Zackqb2

Well I found the problem #5 piston skirt is broken.
