all of my trucks with the exception of the 07 sierra smoke on start up. I want to replace the valve seals on my 76 silverado daily driver and hopefully that will fix the smoke on start up with this truck. I keep reading people prefer some other seals over umbrella. Anyone have a part number for those seals and will they go right on without any type of machining? Thanks
-
positive seals sit directly over the guide and squeegee the oil away from the guide while umbrellas move up and down with the valve. I don't think anyone can give you a part # since you didn't list the specifics about your engine.

engines are posted in signature. All are 350's all stock. The motor in the 76 truck came out of a 76 camaro which is a 350 all stock.

Any autoparts store will give you the choice. Also you can use the orings along with the positive seals
-
no the pimple faced kid at autozone just gave me a blank stare for even asking for the seals to begin with. A lot of times I just walk in with part numbers in hand its alot easier. I guess I can go a few miles up the road to a napa.
-
well I just used umbrella seals and they solved all smoking issues with my 76 silverado.

They couldn't get them for you? They list them on NAPA, Autozone etc

I don't know if they could get them or not. Would using those seals you have pictured require any modifications before putting them on? If not I will try them on one of my other trucks.

No modification at all. Use those on the intake valves as well as o-rings and use umbrellas on the exhausts with o-rings. That is how I do mine every time and they work great.
