JT is not always right apparently
BTW I always wondered why silicone side cover gaskets were first included in a single set together with the (top) valve cover one, but later disappeared from the MOSS offer
In reply to # 3889072 by Brightguy When I first pulled my B into the garage last October it proceeded to puke 3 quarts of motor oil onto the floor. The differential axle and pinion seals leaked along with the rear wheel cylinders, as well as the transmission output shaft. Over the last few months I have replaced all the leaking seals and various gaskets. The most troublesome one was the front tappet galley cover. I tried silicone gaskets, set with RTV the night before, used the rear cover to hold the seal in place while the RTV cured, leaked right away. Small MGA cork gasket, couldn't even get it to seat. Finally cut my own out of 1/16" paper gasket, two layers with a thin, but complete layer of RTV on all surfaces. Replaced valve cover mounting bolt grommets, and at this time I have no engine leaks, no differential leaks, only a small tranny leak which I will attend to when the weather warms up.
