Hi
My friend is having a problem with badly noise from bellhousing side. When engine is cold is silence, but rising when engine warm up. That is no bearing in alternator, but for a first view sounds like that and it would be a piece a cacke. But that is something in bellhousing. I was looking for the answer but did not find exact answer. I pur carbon graphite additive to the engine and noise is overall less noticable.
I know I'll have to disasemble that part of engine but what to looking for?
I record a short movie with that noise: https://youtu.be/jfc2wCBPEYY

Desperately looking for answer.

Monkey nuts. Seriously. The noise got louder when you brought the alternator into view, so it's a good bet that one or more of the cush drive rubbers has collapsed.

Two possible courses of action would be to wear earplugs or to inspect the output shaft components as illustrated and explained on the Tech page in the Portal at the link First renovation of a K100.

Will you pls send me a direct link? I was looking for what you write but could't find. In the mean time found a lot of other post and information but no of them solve definitely the problem.
