I've got a SBC in my '40, and it leaks oil on the drivers side, towar the outside rear corner. I replaced the valve cover gaskets, but it still leaked so I replaced the valve covers, thinking maybe it was warped or something. But it still leaks in the same spot. So two sets of gaskets and a new set of covers and the leak persists. It's not too bad, but it leaks right on the the exhaust manifold so it smokes like crazy burning the oil off. It's strange, because I've never actually seen the leak, I just see the oil burning of the exhaust manifold and sometimes there is oil up on top of the lip of the valve cover, by the bolt.
So I guess I can rule out the valve cover and the gasket, so is it possible the head is warped or damaged in that spot? I didn't notice anything unusual when I had the cover off.
Is there maybe a "heavy duty" type gasket I can use? I think I just used the cork Fel Pro type. Is there a special type sealant I should try with the gasket?
Just looking for ideas. Thanks!
