Hi All,
Tonight, I pulled my valve cover on my 1990 SPG to have a look at the timing chain, etc.
On my '85 I had to use 518 on the VC surfaces by the chain or it would leak oil. On this car, I don't really see any evidence of 518 or silicone. I'm wondering, maybe the Factory Manual's procedure to add silicone was for the older-style gasket with the separate little rubber half-moons. Much of what they tell you to do doesn't make sense with the new gasket, as you can't add silicone where there is now solid rubber.
What is the best practice here?
