P76 oil leaks

[SMOKEY]

Hi Paul, sorry can't help with experience with the P76, but with any motor , has the leak been traced to the rear oil seal or that direction ?, I would check the crank for a groove where the seal runs, what condition are the main bearings in ?, could be to much movement in crank shaft, also check crankshaft thrust bearings, are there any plugs ( rear of camshaft ) or bungs at the back of the block ?, check the engine breathers are not blocked, is the motor getting a bit tired and breathing heavy, if so it could be pressurising sump. The P76 motor had a habbit of cracking the crankshaft ?????, has this been checked ?, could be getting a bit of flex. These motors are getting a bit like me,

OLD,

FITZY.

I have a feeling this seal is a rope seal & they are prone to leaking...no idea if you can replace it inplace or not.
