Re: engine valve seals

What are you working on????

Have you ever used the umbrella style seals? I think they were used on Edsels many years ago. One of my uncles that ran his own garage used them on many engines in the 60's and 70's, he said he never liked the -rubber band style seals- as he called them. Fel-pro used to carry them.

There is no such thing as valve seals on them tractors.
Nor other models with the overhead valve engines from
that era. They did not have seals. And on a flathead no
such thing. Oil is not going to flow up. Max is around .003
So if youre getting oil into the cylinders on an overhead
valve engine its time for a valve job, meaning head
rebuild.

Most ford N tractors we have worked on had valve seals on the intake valves........

It acts like a partial umbrella. oil running down the retainer and keepers are redirected a way some. Umbrella oil control devices look similar but actually look like a small mushroom cap. positive valve seals (used on all cars/trucks now) are teflon rings moving within a rubber seal that allows only a metered quantity to get to the stem. Look up: PC valve stem seals. Jim
