I think it's safe to say it's certainly an issue, especially on cars before 06 when Porsche went to their giant bearing for the IMS. However, it is remediable with the fitment of an aftermarket bearing.

As to comparing a Boxster to an SC, they are totally different cars. The SC's are known to be bullet proof, and have all the charm (take that in both positive and negative light) of the older air cooled cars. The Boxster is a modern car, complete with it's high and low points.

Any model that came with the M96 engine is at risk, regardless of the year, miles, or model. Even the OEM “final” upgrade to the bearing design is known to fail. The options remain to “cross your fingers” or drop about $3K to go to the LN design as a preventative (or alternative) to dropping about three times that if it lets go…… It is all a matter of perspective……..

Not all M96 engines suffer IMS failures...it was mainly an issue with the 3.2L,3.4 & 3.6L engines......I've only seen 1 2.5L IMS failure and a couple of 2.7L IMS failures....

No, all M96 engines can suffer an IMS failure. We have supplied IMS retrofit kits to dealerships who have seen '06-'08 engines with failures, although not as frequent, likely due to relative age. You don't hear about it as much as they are being fixed under warranty still...

Sorry, but they all are capable of suffering the problem, even the latter units with the supposedly "fixed" bearing assembly.

I have a car on my premises now that came in with an IMS failure.. It has a reman engine installed from early 2007 with the 06 and newer IMS update from Porsche.

Its here due to a failed IMS bearing.

I've seen failures from every year and model up to 07 so far, the IMS syndrome is not prejudice what so ever to any particular years or models.

The early cars seem not to have as many IMS failures, they have other similarly devestating MOF..

Consider yourself fortunate; but non everyone else has had the same luck, some have actually had multiple M96 IMS failures in one car……………
