Isn't a oil leak a sign of a problem?
Question from a relative newbie...
So the original question of this thread was how to seal the valve covers to prevent a oil leak. If the engine is healthy, then shouldn't there be no oil behind the covers to leak out. The covers are there to seal the outside environment out? If oil is leaking out, then that would be a sign of an oil leak. Correct? The covers could be loose, warped or cracked but should not leak as there should be no oil there.
So my question is, would you ever just try to seal a leaking valve cover without sourcing the cause for the leak? Wouldn't oil just pool inside until it found another way out?
