You cannot replace it; any remanufactured engine since 2005 has the oversized IMS bearing that cannot be changed without tearing the engine apart.

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.

11 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hi, Just purchased a 99 Carrera with an engine supposedly swapped out in 2008. Can someone decipher the serial number for me? M96 / 01AT66X67208 Thanks in advance!

POST 2Original post

The "AT" indicates that it is a remanufactured engine (AT is an abbreviation of Austausch - German for Exchange); 66X says it is a 1999 Carrera engine; the M96/01 says it is 3.4L

POST 3Original post

I have one of those motors in my 99. It’s been great- only one minor issue after 30k track miles Sent from my iPhone using Tapatalk Pro

POST 4 / ORIGINAL POSTEROriginal post

Thanks for the detail! Would a 2008 remanufactured 996 done in 2008 have the same IMS risks? Should the IMS be replaced?

POST 5Original post

Nope. It has been factory resolved Sent from my iPhone using Tapatalk Pro

You cannot replace it; any remanufactured engine since 2005 has the oversized IMS bearing that cannot be changed without tearing the engine apart. You could, however, remove the flywheel side seal on the bearing so it is lubricated and cooled by the oil mist inside the engine cases.

POST 7 / ORIGINAL POSTEROriginal post

Ok... confused now, If it’s the larger bearing, why pop the seal for oil mist. I’ve searched the forum but don’t see any definite info. I may start a new thread. Yup... ANOTHER IMS thread! ;-)

POST 8Original post

Because you want it to live. Visit the guru on the subject LN Engineering

POST 9 / ORIGINAL POSTEROriginal post

Copy that... Just scheduled a 90k service, clutch r&r, and IMS swap. Thanks again!

POST 10Original post

Again, your IMS cannot be changed out without a total engine rebuild due to its size (it will not fit through the hole in the engine case); but they can remove the rear seal on the bearing so it can lubricate and cool. We have maybe 100 cars running this way, never had one fail.

POST 11 / ORIGINAL POSTEROriginal post

The shop that did the PPI has quoted $2500 to replace it. I assume they know the engine spec, but will follow up with them to confirm. Will reply with their response. Thanks for the heads up.

This is a source reference. Confirm exact model applicability in the original material.
