Oiling pattern on inside of new valve covers.

So are you saying that the valve covers I’m using may not be worthy? View attachment 1715902707
Not necessarily. I'm saying the factory steel LA v. covers are easily deformed by the bolts. If you have thin aluminum sheet metal v. covers, I would think those are even easier to deform with the hold down bolts, so it might be tough to seal those no matter what gaskets you use.
