Ring and Bearing kits rebuiling 4.0

[sinkrun]

I am looking at rering kits online for a 4.0 theres so many choices. Anywhere from 150.00 to 300.00 or so. This is for the 2000 cherokee daily driver no racing off roading etc. Anyone have any suggestions?? Thanks

2000 is a baby. How many miles are on the engine and why do you think it needs a rebuild?

I'm in the midst of a build now, in fact I got the call from the machinist today to inform me of main and cap bearing sizes to order.

 

 

You are going to spend some money and it won't be cheap, half measures will cost you in the long run.

 

I've looked all of the 'kits' and none where to my liking, I want to choose the parts I'm using.

BTW, do your homework, for example-

 

Originally I intended to use Total Seal rings, $180 for the set for the 2.5. A local drag racer told me to look into Hastings rings, so I called everywhere looking for a dealer that carried Hastings, none do. I called Hastings and I've decided to order directly from them for $63 plus shipping.

Come to find out, Hastings supplies Total Seal, TS uses a third oil ring in combination with the second compression ring to make up their set. Hastings does not recommend what TS does but they do supply them.

 

But then,  I dig and dig and dig until I'm satisfied with my decisions.

I was not thinking when I posted its going in the 2000xj its a 96 engine only had about 70,000 on it however the guy I bought it from left it out side under a tarp for a couple years and some water got in one cylinder. The engine in the 2000 has 210,000 on it sounds like a diesel when you start it I overheated it (BAD) when the head cracked there was no water in it at all when we got it towed home. I have ran it for a about a year now all we did was put the 96 head on nothing else and still runs good but is getting quite loud uses and leaks oil. I could most likely just throw it in a run it and be okay. I just want to hone the cylnders and put new rings in so might as well do the bearings. I am not doing a complete rebuild unless something inside looks bad.

That`s what has me concerned about the kits who knows what there putting in and I am the type who insists on USA made parts.

If it got wet as you say.............you will not just get by with a hone and re-ring.........bore is pitted.

Bore is not pitted has a very light discoloration to it. We cleaned it out and dried it and put heavy oil on it last year when we put it away.

[Jeep Driver]

Well, I bought my truck 2.5 years ago and then the engine only had 5K miles on it. I've alway had a problem with blow-by oil getting into the air box and with the VC leaking oil. I swapped the VC to aluminum and then developed a rear main seal leak so I put a new main seal in and new pan gasket.....etc.....rear main continues to leaks due to overpressure of the crank case.

 

The point is I've been chasing round not realizing that I had severe blow-by and loss of compression. I now have 60K miles on it.

 

Supposedly the PO had the engine 'professionally' built........thus my disbelief that I was suffering engine failure.

 

 

 

Now I'm doing the work and I'm spending the money.

 

Who knows what the builder did or did not do.  But I will not go halfassed this time.

Maybe -- maybe not.

 

I once threw a used engine into an old Javelin. It had sat long enough under wet enough conditions that the rings were rusted to the cylinder walls. The car was a clunker that I just wanted to get running, so I pulled the head, soaked the cylinders liberally with penetrating oil for a couple of days, used a 2x4 and a heavy ball pein hammer to break the rings loose, then I cut the ridges off the tops of the cylinders and honed the walls with the pistons in place. Put it back together and after a couple of hours of (re)break-in it didn't even smoke.
