RMS leaking for last 2 years

[j.fro]

There are a couple of considerations for DIY RMS replacement. The biggest is the tool Porsche has developed to check for the crankshaft being off center. This is one that most DIYers can't afford, and if the crankshaft is out of center, replacing the RMS is a waste of time and money.
A second consideration is the Porsche tool for setting the RMS. This tool ensures that the new RMS is both at the proper depth and that it is square to the block all the way around.

Porsche and LN Engineering are treating the IMS in different ways. The LN bearing is a much better bearing, and it is designed to last forever. The Porsche replacement is about the same as the original. Looks like they are treating it as a "wear item" that should be replaced with each clutch replacement. UGH!!
