Hey, I'm wanting to change the oil in the injector pump on my 220D and switch that over to synthetic.
I've found the oil level check plug on the side of the IP. (14mm bolt - that IS the check plug, right?) but I cannot find a drain plug? I'm pretty sure the car is old enough, 1971, that the IP has a seperate oil reservior. There is a drain plug on the IP, right?
