These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1Original post

A clutch replacement is on the horizon for my 911 turbo 2002. Just want to know if this engine is also prone to IMS issues. I am aware that the rear main seal needs to be replace also during that time. What is a Metzger engine? Thanks, Randy. __________________ This post was auto-generated based upon a question asked on our tech article page here:

Your engine does not have IMS Bearing issues. The Mezger engine is the tried and tested Porsche dry sump engine crankcase design which has been used and abused and just keeps on going. Here is a little article which outlines some of Mezger's work. http://jalopnik.com/who-was-the-greatest-engine-designer-in-automotive-hist-1517665150 - Casey

Turbos are the only 996 without the famous IMS issue.

Correction: GT2's and GT3's are on the list too.

POST 5Original post

Hans Metzger was an engineer at Porsche factory. He's the father of the well known GT1 le Mans engine , The GT3 and Turbo 996 are equiped with the same crankcase. No IMS issue to be afraid with it.
