The oil drain pan in my Z4 seems to be stripped; I can't completely tighten the bolt and it is leaking a little bit of oil.
The shop is telling me that I need to completely replace the drain pan, which apparently requires removing the front subframe and is estimated to cost $1500.
According to the mechanic, the drain pan is too thin to do a tap and die rethreading, and that this often fails.
Has anyone ever experienced this? Is full replacement really my only option? Any advice is appreciated.
