Hi All
Castrol straight 50 in the engine, castrol classic 20/50 in the gearbox
I'm in clien to think thats a bit "idiot about face" ????
Straight 50 will make it hard going to start?
I wonder if the oil is leaking from the pump main bearing or somewhere into the timing case??
Normally the amount in the timing case should be a lot less than in the crankcase
Try kicking the engine over with the timing cover off and plugs out and leads shorted to earth
The amount of oil flowing into the timing case should be negligible compared to thet flowing into the crankcase
Normally either 40 or 50 in the gearbox or 90 gear oil
HTH
