Should intake valve

[Ken Cooper]

stem seals be used when building a NOS motor? I'm thinking that if oil is one leading causes of a nitrous motor killing it's self than maybe they should be used. But I don't have alot of room under the retainer for them and was just wondering if I should start looking for a way to get them in there?

P.S. Under normal N/A conditions (16.8 to 1) I have never had oil in the combustion chamber.

On the intake side? Yes.. on the exhaust? I would use them there as well. Try the new style Honda seals. That are very thin walled and fit under the retainer and around a big chunky spring. I know Lukovich has them in stock. They are blue in color if you call him or ask him for the seals I use.. They last a lot longer than the teflon ones as well...
