[Determined]

My understanding was that the Carrera's were known to fail at the valve guides because of oil getting past the valve seals then leaking into the combustion chamber. I could be wrong but I believe I read about it in one of my books and possibly in Pelican's forums or Wayne's book. I don't remember where I read something related to bad valve guides. Let's see if Henry or Wayne himself can help out here.

Best Regards,

Alex
