I used to pull it everytime I had to make a valve adjustment, but its not necessary---just a lot easier . Got to wondering, and then I tried it. You can finagle the valve cover out without pulling the alternator.

Thanks for reading .

With what kind of rockers/polylocks?

-brent

 

I do it with comp pro mags and their locks. But I have cut the hell out of the cover, just for that reason.

 

Excellent point - I overlooked that!

I have no "guts" in the valve covers.

is this possible on a car with stock rockers without demolishing anything?

 

I don't know. Only one way to find out .
