Hi folks,

I've just bought a 2007 Z 3.0i (engine N52). The engine oil pan is leaking. Maybe it's the drain bolt, maybe the pan's thread.

I've torqued the bolt to be sure it wasn't undertorqued but it's not the issue. There's also a crush washer so it's not the issue to.

I'll buy a new genuine drain bolt and gasket (just in case of) but if the issue is on the pan side, what could be the best way to fix it (other than replacing the whole pan)?
- Time Sert?
- Helicoil?
- Oversized bolt (M13)?

Some of them are a No Go?

Thanks in advance.
