BMW Z3 Oil sump with no drain plug

[Peter.N.]

Neither had I but its easy enough to do.

It's my understanding that if you're selling it privately and the seller asks "Are there any problems / defects?" then legally you have to declare them, this is not the case if selling it to a motor trader.

That made me chuckle. What a right load of cobblers.

You don't say if it's a 4 or 6 pot. Not that it makes much odds....both will need the engine suspended and the subframe dropped to get the sump off. Have done this job several times on M50/M52's although not on Z's which might be a bit tighter.

Thanks chaps/chapesses, went down the helicoil route and drilled out the old filler. Left it 24 hours and oil was still dripping(I say oil but it was more like Molasses juice.) Having my doubts whether they actually changed the oil in first place. Flushed through with some cheap oil, cleaned it up, fitted an M8 thread and bolt and it seems to be doing the trick(so far) will keep my eye out and let you know of any problems.
