Archived valve stem seals

[Wyomingcowboy]

My gasket set has 24 blue seals... . there is a difference in appearance, though: one has a single raised lip on the inside while the other has 3 smaller ridges on the inside. I can't compare the ones we took off as they are all gone... . which one is which???????

I just bought a set for my 12 valve. They are all the same. The ones that are on it are two different colors, but the parts guy at Cummins assured me they are the right ones.

Usually the ones with the darker colored springs are for the exhaust valves... ... i don't know if this applies to cummins ones.

These springs are all identical

OK... had to buy a new set that was LABLED!!!! to see the difference. The seal with the single lip is for the exhaust. The one with 5 little ridges (I originally said 3, but it's actually 5) is for the intake. I sure hope this helps someone in the future.
