Heard an annoying slight whistle when doing some power valve experiments today. Found a leak at #5 cylinder between the intake and the head. Ordered some new gaskets from John Mummert. Anyone have a preferred method for aluminum to aluminum gasket installation? Taking the intake of tomorrow for a better look. Ain't this fun?



Update:

Never mind. Couldn't wait until the morning so I took the intake off after dinner. Found a piece of old gasket sitting in the area between the water passage and the intake port holding the manifold up. Must have been from the cast iron B manifold I was using for the break-in. The Best gaskets that I used are pretty thick and not as susceptible to slipping as the thinner stuff on "modern" engines I think. Onward through the fog.
