How difficult should new it be to push a new valve seal over the top of the guide? Never doing this before I wanna ask before I **** something up.

Removed the old seal, and measured the ID .550, the ID of the brand new seal is .530. Wonder if the difference is in old versus new condition? Is this normal as expected?

Trying to get the new seal over the top of the guide I've used hand pressure, then progressed to using a deep socket over the seal. Using what I consider a pretty firm hits on the seal it still doesn't go.


As usual thanks for the assistance.

 

I've always used the GM seals and there is a difference size for the intake vs the exhaust valve. I put a little oil on the seal, slide it down in place and tap it home with a deep socket.

 

I'am not positive on this but I'am pretty sure there is a .550 seal and a .530 seal. I think you have to turn the valve guide down to use the .530. Hopefully somebody that knows for sure will reply for you.

 

Thanks for the info guys. I think I've been able to prove that I have the wrong seals.

It appears I have Compcams PN# 503-16

Doing some more measurements here's the low down.

Valve Stem = .343 = 11/32
Valve Guide OD = .550

Current setup (black rubber color)
Valve seal ID = .553
valve seal OD = .675

Valve seal I'm trying to put on (light blue color)
Valve seal ID = .530
Valve seal OD = .675

It appears I have Comp PN# 503-16, when I actually need 501-16 or 502-16

Thanks again for the help.
