I agree that can be a sign. But I'm an optimist right now...

If that was the case I would expect to see oil on the sparkplugs. I'll pull and check them later. I did some searches and saw where this can be vacuum related as well.

I also have a new set of pressure regulator valves to install as well. I read those things can cause issues with the intake getting gummed up.

The car never smoked and ran well.
