Yep I will check. Is any thread lock recommended like Loctite Blue 242

Donut type is 20 Nm

20Nm

Now what about Loctite? the thread has nothing to do with the signal it is the face to face contact that matters. I see no reason that the Loctite will do any harm?

[Mikes2]

I never use Loctite on any fasteners on the engine as it's not required. If you put Loctite on the threads, how can you apply the correct 20 Nm
