Fel-Pro OS34308R Oil Pan Gasket Set

I installed this with the high flow oil pump and rear main seal on a 1999 Jeep Cherokee 4.0. Might as well do them all if you are wrestling that oil pan off. If you are installing all three do not use the tools with the oil pan gasket until you are sure that the oil pump and pickup don't keep the pan from sealing right. It's a pain to keep taking off the oil pan with those tabs. I had to use my special hammer to beat the pan so the pump would clear. Look up the videos and you'll see what I mean. I packed the pump with vaseline to help prime it. I'm not sure if it was needed, but better safe than sorry. As soon as I started my jeep the pressure immediately went up to 60 PSI, and has settled to 40 psi at idle (before it would drop to 20 psi at idle). It does go high when you press the pedal, but never above 80 psi because of the relief valve. The pump is well made. There is a tight tolerance to install the pickup tube. I put the pickup in the freezer overnight to shrink it. Then you can use a wrench that fits above the collar and hit the wrench with a hammer to install it. You might also have to slightly bend the pickup to allow the oil pan to fully seal. Good lubrication and no leaks!

Worked great on my old 258/4.2L

I’ve bought this gasket several times and this is the first time that came in a grey color! Looks the same premium quality though.

Perfect fit for a 98 TJ with the 4.0 engine.

I like Fel-Pro products as they are top quality.
