Valve Stem Oil Seals

devoulley · 04-30-2012, 07:28 PM

I have a 1990 CQ that I am about to attempt replacing the stem seals. Does anyone have any advice or direction?

Are you planning on doing it with the head still on the block?

No, I plan to take the head off, but if its easier to do with it on I will. I don't know what to do really

Much easier with the head off IMO. Though I've never tried with it on as it's enough of a PITA with it removed even w/ the proper tools. You'll a need valve spring compressor, a pair seal removal pliers and a suitable tool to install the new seals. Obviously it would also be a good idea to have the head decked or at the least very checked for warpage by a good machine shop.
A valve job wouldn't hurt either. Other than that maybe check youtube for some videos on how to replace valve stem seals.
