I just had my heads redone on a 3.0. I am getting a leak from the rear right side of the vehicle. Upon further investigation I can see oil coming from what looks like the bearing cap. It could hopefully be the valve cover. I did use sealant on the bearing cap but only did the rubber seal on the valve cover. I have read that some people put a bit of sealant in the corner of the valve cover.

I plan on taking it apart tomorrow. My question is will it hurt the cam if I take only the number 3 cap off and reseal it or do I need to take the timing belt off and all of the caps and retorque them?

 

the only bearing caps that can leak are the end ones. i would say it is either the valve cover leaking or they milled the heads to much and it is leaking at the oil returns at the head gasket/ w/ i hope that is not the case.

 

i took it apart and I believe it is the valve cover.

thanks

 

i like to use a little rtv on valve cover seals, ill put a real thin bead inside the seal grove, seat the seal in the grove, then smear a real light coating on the outside of the seal. make sure the mating surface is clean, and you should put a dab on each corner of the front and rear cam seals.

 

i am having the same problem except it seems to be leaking from the cam cap..i have replaced the rear cam plug and cam plug bracket and it still leak from the same area..i know 100percent it is not the valve cover..any help?..

 

I have read some post that say to put some sealer around the cap.
