Doug- I am currently having the same problem with my V8. I intended to replace the valve cover gaskets, and query the long term listers for a reference to another "well known" leak source which I vaguely recall was somwhere at the back of the engine. While we are at it perhaps some one will give us a contact for valve cover gaskets etc at a resonable price. Frank Santoro 1990 V8 Kingsville Md
