I'm wanting ppls input that have some experience and knowledge with the 4.0 gaskets so with that being said what's everybody's opinion on which brand if these gaskets I should buy let's start here my jeep is obviously a Cherokee it's a 98 4.0 with about 198K I'm getting ready to replace the intake manifold gasket, exhaust manifold gasket,head gasket,rear main seal,oil filter adapter o rings,and oil pan gasket, and also anybody know a damn good timing chain replacement ?

Felpro hands down.

On my 90 the RM seal and the manifold gaskets Napa handed me seem fine.

For the valve cover and pan, Felpro makes a nice, thick, (blue) one piece gasket that's ****. If there are choices, it's the spendy one.

For Renix adapter O rings there is a Crown Automotive kit that's good. I'd guess they have one for HO as well. Also if you have a dealer handy you might price them there. The kits at the cheapo parts stores are worthless.
Here's the sizes, but the people selling might not even know what they have.

91-01 HO Model Orings
0.676 x 0.070 AS568 size -017
0.859 x 0.139 AS568 size -212
2.484 x 0.139 AS568 size -230

I'd suggest that since timing chains rarely wear out, about any replacement would do. I did notice them cheap on Rockauto

While you are at Napa you might check on a vacuum harness. I gather they have them and so long as you're going that far....

So there's a start, have fun!

Fel-pro. Got a complete set from NAPA for $85.

Awesome! Hopefully I can get some more insight on the other few gaskets I've heard a few ppl say only Delphi was good for the valve cover and oil pan myself too

40 yrs and have found no better than these.


FWIW I have used there SBC valve cover gaskets with the HD center layer inside for a full year removing them every week to run the valves, never a leak. Then gave them to friends to use on there cars still good but at the time they cost about $40 a set and worth every cent.

BettyWhite98

Make it easy, Betty. Get Fel-Pro. Done.


Not that there aren't other good choices, and maybe even equally good choices, but there are no better choices.

We're beating a dead horse. Go Felpro and get on with it.
