I would have finished checking the 1954 235 engine but 2 different starters smoked. 4 compression strokes per cylinder test and then rest for a few minutes. I need to rebuild the starters anyway. Per 12-21. As far as the engine rings and or valves leak. I have never heard this engine run. Oil is ok not green or brown. Jims Automotive Machine in Brunswick has 2 of my 848 heads he is machining for me. I plan on having him machine this 235 and if needed install a set of 30 under for the crank that I purchased from The Filling Station. Thoughts.
