The thing that worries me is, if I do return this and get a motor from another donor, I may end up with the same issue potentially. Is this corrosion a non-issue since it's behind the o-ring on the block/pump interface, or should I be concerned here?

That doesn't look too unusual for an engine that's been sitting- see if you can look in a few other ways. Pop the heater pipe off the back of the head, maybe.
The M42 never had a plastic oil filter cover, tho- that showed up with the M44,
and the plastic heater pipe on the back of the head.
I have 12-94 and 7-95 318's, and both have aluminum oil filter covers.
tnow, sometimes I just mess with people. It's more entertaining that way. george graves

All I want to know is, should I not be worried about this corrosion because it's past the seal, or should I return this and look for something better?1991 BMW 318i Alpinweiß II Slicktop 231,000 Miles Build date: Wednesday, 1/30/1991

If you are okay doing a full reseal and a real cleaning before installing the engine you can certainly run it. However, I would never personally want to buy an engine that has been sitting over one that has been run/pulled recently.
The corrosion isn't too worrying to me, but the information that the engine seller passed on certain does give me pause.

What information are you referencing that gives you pause? Sourcing this engine was a pain, and I'd rather not pull a motor from a nice running E36, plus there's no guarantee it's in any better shape with the age of these motorsLast edited by Gloff; 05-12-2019, 01:38 PM.1991 BMW 318i Alpinweiß II Slicktop 231,000 Miles Build date: Wednesday, 1/30/1991

Well, engines that are pulled by a wrecker are a complete unknown, and can have serious internal issues. Remember, these cars were likely crashed, possibly quite badly, which can lead to all sorts of problems, or conversely, no issues at all. Whereas, an engine pulled from a recently operable vehicle is likely to be closer to drop in a go sort of shape.
Either route is fine, and if engines are hard to source where you are you have to take what you can get, just as long as you are fully aware that it may entail more work/cost.
Let's also remember that there are very few nice E36 318i models at this point, so don't feel too bad about parting one.

Makes sense, this one looks good and all in all wasn't that expensive, if it's a dud, guess I'll go the part out an E36 to save an E30 route thanks for the help!1991 BMW 318i Alpinweiß II Slicktop 231,000 Miles Build date: Wednesday, 1/30/1991

Another question too: Are the Oil Filter housings interchangable? I already have a bunch of filters for the aluminum style bolt through filter housing. I see on RealOEM that the outlet uses a "bushing" with two o-rings, and the aluminum style uses one o-ring on a pressed in fitting. Is the plastic style a significant upgrade?1991 BMW 318i Alpinweiß II Slicktop 231,000 Miles Build date: Wednesday, 1/30/1991

Don't think there is any real value in changing filter canister types, and when it comes to parts diagrams at or near interchange years you really need to verify what's in there before ordering bits.1991 BMW 318i Alpinweiß II Slicktop 231,000 Miles Build date: Wednesday, 1/30/1991

Would you replace the front crank hub? The one one the new engine is lightly scored from the seal, and a new one is $47.
Also, the rear main has a kit available with a pre-pressed rear main seal and new carrier. I thought I read something about setting it at a different depth to avoid putting it in the same scoring mark on the crank, how would I go about re-setting the depth if I order the kit? Hope that makes sense.1991 BMW 318i Alpinweiß II Slicktop 231,000 Miles Build date: Wednesday, 1/30/1991
