I took my vlave cover off to adjust my valve lash. When I pulled the valve cover, I discovered this yellowish white goo under on the underside of the cover. It was only under the cover and not on the rocker arms or valve assembly. Can someone tell me what this is and how I may fix it?

could it have something to do w/ water or condesation or something? do u have a breather on that side?

Yeah, there is a breather on that side.

Nevermind, I talked to a buddy of mine, he said it is a water/oil emulsion formed from condensate. I checked my dipstick for water and found it free of h2o. Guess it is condensation.
