Today on the way back from a nice sailing, I felt a slight vibration when I raised engine rpm, I ignored. When I lowered RPM to approach the slip, engine stopped.
I opened valve cover, all just looked fine and beautiful to me. But when I rotate crank, it is extremely hard to rotate crankshaft only when cylinder 1 valves are moving. This hard to move crankshaft at some point has been always like this since I first tried it. Now I see it is related to cylinder 1.
This seems some kind of clue to me. I am not starting engine since then and can't now 'cause valve cover gasket is not reusable anymore.
Would anyone tell me where the problem seems to be? I'm praying problem can be solved by a simple parts replacement.
PS: one more thing, I once before tried to rotate crankshaft when I removed injectors from cylinder 1 and 2 and was same as above.
