" I have just removed a 1971 Palmer P-60 from a Columbia sloop that had been inoperative for one year. The problem is with a few valves that refuse to close due to salt water immersion.
I also noticed salt water spouting out of the spark plug holes, hmmm. I replaced the headgasket, but the porblem persists.
What is the best approach? Is it possible that the intake/exhaust manifold has cracked or "back siphoning from a failed wet exhaust system?
Is there a good test for this condition?
How does one free up the valves?
Any input would be helpful, Thanks. "
