The stuck intake valve saga has been continuing quietly for several weeks now. Here is how it went:
1. Got the Junkpile B running. Valves stuck after sitting overnight.
2. Removed head, cleaned up GOO in the head and re-installed. Ran good, Valves stuck the next day.
3. Put a different head on. Valves stuck again.
4. Soaked original head in tank overnight. Cleaned it all up, lapped valves. Re-installed it on the car. BEFORE I ever cranked it up, I changed the gas tank!!! Now it runs good, after sitting all night in subfreezing temperatures. The old tank has about 1/16 of an inch of GOO in the bottom. When I say GOO, this stuff looks like the thick, brown, sticky Permatex Gasket stuff.
As I was removing the valves from the head that had soaked overnight, Frankenstang (Junkpile Spitfire Guy) was there.
As I was removing one of the intake valves, he remarked that he had never seen any so stuck. I used a 3 pound hammer and punch to drive the valves out. There was sticky black stuff on the stems that glued them in place. When everything was cleaned, they slid perfectly.
So...Lesson learned. Check the "empty" gas tank that has been sitting for a few years. Junkpile B due to hit the road this week (fingers and toes crossed).
Bruce, Glad to have it all figured out)
