We used the GM Valve Cover Adapters (PN 24502540) on our GM 330/350 Vortec Crate Motor so we could use "MOON" brand nostalgia finned aluminum valve covers (Outside Flange Mount). We love the "LOOKS"!
When we fired up the motor for the first time last Friday, the passenger side valve cover (lower edge) leaked quite a bit. As I tightened the bolts, it started to leak more, eased off and it slowed down. We used Moroso Valve Cover Gaskets (PN 93020-blue in color, rubber?) which were furnished by Sallee Chevrolet when we ordered the Engine/Trans. The drivers side didn't leak=YET.
The inside bottom edge of the valve covers appears flat (used a very straight aluminum straight edge).
What possibly is causing this? Can we purchase a valve cover gasket that can be used with sealants (Silicone, etc., or?).
Any and all info will be greatly appreciated.
