Search for the procedure. I’d say what I think it involves but I’m not positive I have it correct and don’t want to mislead. .
I thought about it as well, as for right now I spotted a leak coming from the valve cover spark plug seal on cylinder #4, I mean, all other 3 are sealing perfectly so that might be something. I’m thinking about replacing the valve cover seals and re-test to see if there is other leaks.
