Next to which oil to use, this is always a contentious subject. Yes, there have been crankshaft failures associated with removing the harmonic dampening of the dual mass flywheel, Porsche released a TSB warning dealers to not warranty such damage if a single mass flywheel was in use.

One of the biggest issues is the lightweight flywheel itself, we have seen some that were several grams out of balance themselves right out of the box. That could be corrected by having whoever does your engine balancing spin it up and correct the imbalance (including the new clutch assembly), but not everyone does that, and ultimately pays the price.

Proceed at your own risk.
