Bad valve seal after cam install Noticed an oil consumption issue a few months after doing a cam install. Installed titanium retainers and PRC dual springs + PRC stem seals from Texas Speed. I used a 12mm socket to install them and must have screwed one up by accident.
Pulled the valve covers, can't see anything without removing the springs. Maybe with the single springs you can see through the coils, but the dual springs you really can't see much. So I pulled the plugs and here's what I found.
Driver side plugs. 1,3,5,7 - looks like 5 is the culprit. the ceramic on 1 is a little darkened as well.
Passneger side. 8,6,4,2 - 2 looks a little lean, 4 also looks not quite perfect, maybe also leaking oil?
There's some oil on the threads of most of the plugs. I'm guessing that's just some of the grease I applied when I installed that eventually melted with the heat. I can't really tell if the plugs that are sort of darkening is from burning oil or just normal wear of the plugs. Not sure if I should change the seal on just #5 or all the ones that are dark.
