engine and drivetrain Oil Pump Fit Question

[rasmith9]

There is an oil pump on ebay that is used but barely, looks to be in good condition. It is listed as fitting a 1.6, 1.8, 2.0 enginges. I am in the process of gathering all the parts to do a rebuild on a 1984 M10 going into a 318i and understand oil pumps are hard to come by. Would these pumps fit universally (i.e. would it fit my engine)?

Also, how big a risk would I be taking on a used oil pump?

Thanks.

USED pump is the key

I wouldn't pay more than $25 for a used pump- they tend to be one of the

first things in an engine to get chewed up, since they pump unfiltered

oil...

Thanks - your responses appreciated, no go for the USED pump.

There are specs in the BMW shop manual for the various clearances inside the oil pump--and if something is worn, the internal drive gears that actually pump the oil are available as spare parts from BMW--much cheaper than a whole pump. New pumps are now north of $500...

The original pump on my 203k engine was still well within specs and pumped a steady 60 psi at highway speeds when I pulled the engine for a rebuild (not due to oil pump failure!)

Make sure to ask for some good pics before you buy that used pump ;-).

Looked good on the inside
