    Default M30/535i oil pan internal view

    Can somebody please post pics or drawings of the INSIDE of an M30 oil pan?

    Or, if you have links to such pics, or can PM them to me, that would be MOST helpful.

    I'm curious about the shape, size, location of whatever internal baffles, etc. may be on the inside of a 535i oil pan.

    There aren't many baffles to speak of, just a small rim around the sump area.

    I've got an M30 pan around here somewhere- I'll see if I can get some pics.

    Default Bart - Here you go

    Pics of the inside of the oil pan.

    Unfortunately, I don't think this bodes well to get the missing nut from the bottom. It sure looks like the nut would drop into a little tray at the front of the picture. That is, between the rivets at the front there's a little tray area. Bottom of it is the cast aluminum pan and it's protected by the windage tray. The red thing is a plastic plug there the oil level sender sits.

    My guess - better to try to get it from the top.



    Hopefully you already have it out and this is all moot.


    Another pic looking down the length of the pan, front to back.

    Thanks, MUCHO, Jeff.

    This helps a bunch: Knowing more about the internal geometry, maybe I can drag a powerful magnet from the outside of the alu. pan near the rivets, pick up the nut, then drag it around to above the hole for the oil level indicator, then down to retreive the nut through the hole. That's the theory, at least.

    So far, all I've been able to see is a bit up through the oil indicator hole, which is darker than a dead mule's ass. (and about as much fun)

    Glad this helps.... I've come close to dropping the cam gear bolts down the front of the cover. This will just remind me one more time to cram a rag in there..

    Let us know how you finally get it out...

    Well, spent quite a bit of time with a flashlight, dental mirror, and magnet on a length of coat hangar wire, fishing for the lost nut via the oil level sender hole. No luck whatever. This task is REALLY getting old.

    Next, to remove the timing chain cover to search for the lost nut, and replace chain and tensioner/guide rail while in there.

    As it happens, there is not enough room between the big 36mm nut and the AC condensor (with rad. removed), to fit my friend's impact wrench. (needs ~12") So, gotta get a crankshaft securing tool and do the breaker bar thing to remove the 36 mm nut. Happy day.

    Yeah..pretty gross. That's the extra oil pan from all the motor swaps. Block and head are long gone but I haven't had the heart to toss pan out. Beautiful casting work. Soooo...it lives now in the woodpile waiting for a new home and a good cleaning.

    Anyone need an M30b35 oil pan?
