Hi all.
Bough my m52 engine complete with what I thought to be an e34 m50 front hanging sump. I always figured I'd been given the incorrect dipstick with it as the oil level would read over the full mark so I measured out exactly 6.5ltrs by the jug and marked a new 'full' line on the stick.
It's bugged me for ages and I've not actually used the car since building it yet, I looked into it further and noticed a date stamp of 1997 on the sump but no visible part number. The part number on the level sensor fitted comes up as either e39 or e38 M52! So I assume now I have a 728i sump.
After quite a bit of searching about the 728 only holds 5.8ltrs of oil!
Worth noting if anybody picks up the same sump.
Interesting point if using an e38 728i sump.

The only difference that I know of with the sumps is the hole that the dipstick goes through.
The difference between an oil change and oil capacity in an M52 is approx half a litre BTW, so I would always use the correct dipstick and tube as reference rather than measuring what your putting in
