Dave, thanks for your comment. The source of leakage is all too visible! The valve cover challenge has been discussed on the forum many a time, getting a flat tin cover and not distorting it by over tightening in a desparate attempt to make oil tight are two important issues. I found a cast ali cover at a jumble, and with the silicon gasket made from high spec baking silicon sheet solved that problem. Now, silicon gaskets between crank case and block have been a source of debate.
