I noticed this week when I pulled the truck into the shop that my valve cover gasket started to leak on both sides. Not bad but still leaking reguardless.

If your valve cover is leaky and it is not improperly installed, then it is an indication of crank case fumes building up in the engine. This is a very bad thing to allow.

Crank case fumes are absolutely nothing to play around with. -= ANY allowance of pressure buildup inside that engine will wipe out the overhead cam, and also destroy the turbocharger.


What kind of crank case filter are you running?.. is it the paper one?.. or the newer maintenance-free one?.

-= I suggest that everyone uses the maintenence-free crank case filter from cummins...

Otherwise, gut the paper element out of paper one all the way so that only its outer frame/gasket remains and put it back in without the element.
