My Cadillac 1958 Convertible Repairs
Just discovered that my left valve cover gasket was leaking and probably had done so for a while. Tried last year to seal with Permatex sealant but that did not help, still seeping from back lower corner and dripping on to exhaust manifold which generates burnt oil fumes. It just got removing the old gasket now almost impossible….
When studying this closely I noticed that all gaskets I have from several suppliers all seems to be a little thin to fill out the space in the valve cover and then the legde on the rear bottom side of the head prevents the gasket to seal. See arrow in picture below.
