Interesting note on the rear main seal for this engine (and MGA's were the same). There is no 'rear main seal' per se. Dusty is trimming the SIDE seals of the rear main cap. The '
oil seal' method at the crankshaft is simply a threaded type groove on the crank that runs really close to the block and rear main cap and 'throws' the
oil forward back into the engine. When the motor is stopped residual
oil slowly seeps out the rear main and 'leaks', as per specs! It is designed to leak, what a concept!!
The Healey manual notes care should be taken to make sure the hole in the bottom of the bell housing is open so the oil can 'drain' (you know, onto the garage floor)!
