Well at least it's true they no longer have the IMS in the engines, whether the new design is bulletproof remains to be seen. My engine runs fantastic and it's the scary low mileage 2.5 or so they say...

Boxsters have no more engine problems than any other car on the market. I will give my 99' Nissan Altima a thumbs up. Just under 100,000 miles with no engine work. 3 batteries, 3 sets of brake pads and 3 sets of tires. Regular oil changes every 5K miles just might be the key. One thing that drove to the Altima was they used a timing chain that is bathed in oil. Not those crazy belts that break.

I do not buy that at all. I don't believe the 20% failure rate, but I wouldn't be surprised at all at 2-5%. And by failure rate I don't mean $2k repair and you are out the door, we are talking $10k and up complete rebuilds/replacements. By any statistical measure 2-5% for complete failures is horrific compared to other top cars on the market.

Yes, I am one of the one that has experienced an IMS failure and am dealing with aftermath of that now on a 2004 car with 20k miles. However, Excellence Magazine has devoted 2 full articles (with a 3rd one due later this year) to the IMS issue and the lead guy dealing with the repairs/upgrades (Flat 6) is working on a 2 month to almost 1 year back-log depending on what is needed. Those facts alone tell me the issue is not insignificant.

I wonder if the 04 SE in particular, was a problem edition. I've seen at least 04 Special Edition Boxsters with IMS failures on various Pcar forums over the years. Was yours an SE?

Yes, mine is an SE, but based on what my research has turned up its not an SE problem, it's any M96 motor installed in the Boxster and Carrera models.

Yep, I realize it affects all M96 based engines. Just that I've seen a lot of 04 SEs pop up as being hit with it. Thought maybe a bad batch of bolts/bearings that production run.

This is my first Porsche so bear with me here, but until I was researching this car I had never even heard of an Intermediate Shaft before. I've never had a car or motorcycle with a boxer type engine before, so I assume it's something unique to that design.
From what I've learned on this forum, I was surprised to see the bearing that fails is such a small unit. What function does the IMS perform in the engine?
