valve covers

[Teo]

My R65 rght valve cover started leaking oil on the upper forward side.  It popped little droplettes of oil out onto the exhaust header at stoplights.

I found the gasket had deformed and receded into the cavity - apparently the mating surfaces were not parallel enough.

I replaced the gasket and all worked well for a few hundred mikes til the gasket deformed the same way as the first.  I then assumed the head or  valve cover surface was slight deformed.  

I took out the studs and verified the valve cover surface flat.  To resolve the leak I put silicon gasket sealer on the gasket surface - fixed.

Hey All,

Just wanted to give everyone an update on this.  Seems that it was the valve covers.  I replaced them with a used set and they are not gushing oil as they were before.  Guess those can warp.  Only a few drips so far compared to a puddle.  A litttle more riding and I bet they'll seal up fine.

Cheers.

I had similar issues with my R100/7 - I bought some thicker, black silicone gaskets from Realgasket.com and that took care of the problem.
