Valve Covers

How tightly should the valve covers be tightened down? I had mine torqued pretty tight. A shop did some work on the car, and decided to check my shim clearances. When I drove it home there was oil all over the top of the engine and I noticed that the hold downs were only finger tight.

Thanks Mark,

That's not very tight - what would cause leakage? I seem to have a lot!

finger tight is not tight at all

If you over tightened the covers, they may be warped. Check them on a granite block like what a machine shop has. You may have squeezed the cork gasket out at the tight spots. I use a gasket cement to glue the gasket down on one side only. this keeps it from squeezing out of place when tightened.

Thanks - I'll pull them off an check flatness. Mine have a rubber gasket, though, not cork.

A good cast and machined table saw top is flat enough to check them, I use my Delta Unisaw for this sort of thing.
