Pinto Valve Stem Seals


Recommended Posts


Is it possible to use the CVH top hat valve stem seals on the OHC head? I have just tried but the seals seem too small. The internal diameter of the seal is 14.5mm but the outside diameter on the seat is about 16.5mm.

I thought this was used as an upgrade but maybe I got it wrong.

Hi Graeme. I cannot remember the sizes. But they worked perfectly. Much better than the pinto way of doing things. I'm sure someone will be along shortly with the sizes answer.
