I'm just suggesting that the repair could be done by going to M7 without having to take apart the Vanos.

He is saying you can tap the thread from m6x1 to m7x1 with the vanos still attached.89 E30 325is Lachs Silber - currently M20B31, M20B33 in the works, stroked to the hilt...

Done.
I pulled the radiator and hood for access, plus removed the VANOS unit.
The exhaust stud wouldn't have worked because the stud is an M6x60 and the exhaust stud is M7x39. I think it's the longest studs that pulled because they're clamping the thickest section of Aluminum, hence the greatest extra force from thermal expansion.
Seems fine now, anyway.
Edit: I helicoiled to use the original studLast edited by hoveringuy; 12-04-2018, 09:35 PM.
