L28 valve seal???


Recommended Posts

I know that my retainers hit my valve stem seals with an aftermarket cam, springs, and retainers (490 lift cam and Schneider springs and retainers in my case). Do a search and you'll find a fairly recent post where options for this were discussed. You can use a Datsun A series seal, or a Ford 2.9L V6 seal. The Ford seal looked like the way to go IMO.

 

Barring some kind of contact I can't think of a reason why this would happen. Since it has, you should probably replace them all, and these lower profile seals would be a good way to ensure that it doesn't happen again. You might want to take a close look at the valve stems and make sure they aren't all scratched up before you install the new seals.
