I did my very first valve adjustment today and have the bandaids on my fingers to prove it. Pretty proud of myself.
While I was at it, I replaced both valve covers and bails, this due to a persistent oil drip-drip-drip from the left valve cover. Last time I did this, trying to solve the same problem, I just used a new gasket. Didn't do any good. This time, the Wonderbus got new gaskets (w/ gasket compound between gasket and cover), new steel covers and nice pretty new bails.
Drip remains. And no, I am not talking about myself.
Other than welding the cover to the head, what else might I try?
