Now it's time to get to grips with the oil loss. There is the oil loss at the gearbox outlet. Since the oil leaks between the ball housing and the gimbal, the leak is probably the rear main bearing. I can't do much about that for now without removing the engine or at least the drive shaft. However, I prefer to have the motor, which is currently under repair, fitted with a sealed ball bearing. This is not original, but I find such an oil loss is also not acceptable.
When trying to tighten the 4 screws of the ball housing, I feel that the screws no longer grip properly. Maybe I should cut the threads to the next larger metric size.
But oil is leaking not only from the drive shaft, but also along the oil pan gasket to the engine block. This oil leakage has become more.
I retighten all the screws of the oil pan and am amazed that each screw can be retightened more than one turn. Presumably, the silicone used additionally for sealing is the reason.
However, the first test drive does not yet show the desired success. Oil is still leaking from the oil pan. The car now remains in the workshop until the problem is solved satisfactorily.
