M54 Madness, the remix

[Jaker]

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

I guess I'm not understanding the advantage of using M7 in place of M6.

He is saying you can tap the thread from m6x1 to m7x1 with the vanos still attached.

Couldn't I do that with M6 as well?

Edit: Oh, he's saying tap for M7 directly without using a helicoil.

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 stud

Mine was single Vanos stuff, and the studs I used were significantly longer than the ones that were stripped. I might have been using intake studs. Either way it's fixed and that's all that matters. What did you end up doing? Helicoil?
