There is a change in the Bosch and that is where the oil pickup is located, direct off the machined face plate of the oil pump, it's cast into the plate. The GEMS pickup is located on the block so the oil suction side is different between the two. The actual covers are identical except for that one change. Bummah. It's possible to grab a pickup off a Bosch and block off the pickup port on the GEMS block I suppose but..... I don't know anyone who's tried it.

Well that is a bummer... Guess I will be fishing at pick and pull as I often do nowadays for a "better" cover than I got for my rebuild next year. Thanks for the answer. I will try and remember to post the pics of my bearings tonight. It will be embarrasing and I am sure I will get another recommendation to mic' the journals cause they are bad... Might be the reason why I haven't yet.

Hard to tell from looking at a picture but good to know...... the cost of a new cover kills it for me. I'd yak with a machinist before I'd ever spend that much on a new oil seal holder. Pretty copper shells. I'd be inclined to slosh some Rotella T6 in the cc, light probably wouldn't even flicker. 10 seconds and the top end is taking it in the shorts at less than 8 psi.
