Whew! Glad I checked in here before I shut the laptop cover for the night (it's 11 pm now).

Who'da thunk having an OLD Boxster engine would be a good thing?

Good job Jim!

Sometimes, new and improved isn't!

This is very interesting indeed. So for those of us who have E-gas cars, how much should we worry about IMS failure? If my motor has already made it over 50K does that put me in any better shape (as in, I got a "good" motor since it seems a lot fail at low mileage)? Is there any evidence the 3.2 is less at risk than the 2.7 or vice versa?

The latest version seal aka the Cayenne style is in my hand. The green plastic ring in the middle of the seal is an installation aid and the ring is later removed.

Gee. It's so small and unassuming. Who would think that it could kill your engine?

Thanks for posting the pic!

On Renntech there was a thread discussing this issue as well:

http://www.renntech.org/forums/index.php?showtopic=15021

Here's a nugget from that thread..

"I don't know if the issue is completely resolved or not but the intermediate shaft has been redesigned. I cant say when exactly it was introduced or give an engine number range but the new style is very easy to recognize as the nut on the end is now something like a 24mm instead of the old 13mm. Anyhow pretty much all of the 05 and early 06s still have the old style shaft so 9x7's are still very susceptible to failure. For what its worth I have not seen a new style intermediate shaft fail, or leak for that matter. "

Does anybody have any more information on what the redesign actually is, and what dates the "new design" took over? Has anyone heard of a a failure of the new design?

I would have to guess this was done when they tweaked the motor for the 987 launch. My neighbors 04 model lost an engine due to IMS failure so not in that year!

Hi fellow Boxster owners.

My 2005 Boxster S broke down and had to be towed to my local Porsche dealer. They said the Intermediate Shaft was broken and most likely needed a new engine. My 4 year warranty just expired 3 months ago. The dealer said they will try to get Porsche corporate to give a replacement engine for goodwill (no cost) and that i would have to pay for labor to replace it ($2,200).
Does this sound right ?
Seems as if there is a systematic problem / issue w Porsche's intermediate shaft.
Any advice?

This could be my last Porsche is this issue is not satisfactorily and pleasantly resolved.

Help.

You have the exact same problem that several of our customers have had.. Your Porsche Dealer is like the one mentioned in the testimonial on the front page of my site, at the bottom www.flat6innovations.com ... We saved his engine and his money when the same exact issue struck..

We **may** be able to save yours, but Porsche can't and won't try to.. Most don't know that the technology exists because their information supply source is limited to themselves.

These pics describe your scenario... Explore the possibilities outside Porsche before going further. if you just have oil loss, minor noise and etc the bearing may possibly be worth extracting and replacing. This is done with the engine in the car as depicted here.
