A question that I am not sure how to even ask...

On a 51 year old engine?!? Yes. You're going to have to pull the valve cover and see what's going on.



There is currently another thread active about a sludged up motor and different opinions and ideas of how to clean it out. I would try to find that thread. Lots of good ideas. Good luck!

Thanks much for the suggestion. I'll head over there to that thread. I've never seen sludge that bad, but then again, my family was always big about maintaining cars per schedules. I hadn't bought a used car in quite a while, so you may be on target.

I'll pull the head this week, weather permitting. I did run a probe into the valve cover, even past the baffle, but got nothing back. Then again, there's a lot of square inches under that cover to hide a world of oil and sins...
