Another IMS bearing thread

He charges $1400 to do this on cars with Tiptronic, which includes all parts

The part he is center punching is the only thing holding the oil pump drive key from falling into the IMS shaft during operation. I see these failures occur without the assistance of a center punch.

It helps to understand the anatomy of the patient before performing the surgical procedure.

My Indy mechanic is from Germany where he was Porsche trained. He was the lead mechanic for Brumos Porsche in Jacksonville for 24 years and had his hand in every engine that was built and used there for all of those years.

Has he experienced an M96 engine that failed due to the oil pump hex key falling into the IMS tube?

To fully understnd the anatomy requires cutting open components for cross sectional views.

Experience helps, but it isn't a guarantee. For example, consider the years of experience the Porsche team had when they designed the IMS in the first place.

Agreed. , although according to my Porsche mechanic friend there is a lot of pressure and decisions being made by bean counters. That is one of the reasons he left corporate after 24 years.
