I own a 78 Delta-88 with 403. She runs and runs and runs. 200k-400k miles (speedo doesn't work).
Why does exhaust blow out the valve cover?
I replaced the gaskets, but the passenger side cover still puffs quite a bit of exhaust. Could be bent cover. I will try a second gasket.
But why exhaust?
I replaced the PCV valve and tubing is not restricted.
The head doesn't look cracked. There is a patch on the valve cover where the paint burnt off directly over the exhaust leak. What does this indicate?
have the same problem?
