The engine in my Stag was rebuilt by a well known professional garage 4years ago and 9500 miles, It recently started dripping oil from what I thought was the oil pump seal. I removed the pump and replaced the seal, and was made aware at this time that the oil pressure I had was too high, being some 70 psi when cold. I acquired a correctly rated oil pressure pump spring from Robsport and reassembled it. After fitting the pressure was a more reasonable 50 psi, but unfortunately the oil leak was still apparent. Not much, but it dripped straight onto the hot exhaust. Eventually, after running the engine upto temperature a few times on the ramp, I traced the oil lead to the cam cover gasket. When I restarted the car it was like there was a flat battery, and the engine tried to turn over, but would not. I checked the battery, and all was ok, so I tried again and it turned, a bit reluctant, but then properly, but it would not fire. After some investigation I found that the distributor was not rotating. Having now removed it, I can see the jackshaft gear is stationary.
This leaves two questions:
1. Is there some way that I caused the oil pump / distributor drive to seize up when I replaced the pump?
2. Is the jackshaft itself likely to be fractured, or can the drive gearing rotate without turning the shaft somehow.
Any thoughts gratefully received.
