Hello,
I have a 1971 220D and need to know the procedure to check and add oil to my IP. I looked at my owners manual and it said to unscrew the hand pump a few turns and add oil till it comes out of an overflow hole? I filled a small oil squirt can 2 times and emptied it but I never saw any oil come out. I'm afraid to keep adding oil and overfilling it.

Thanks
