It looks like a scary ratio of the 2004 SE's have had issues.....not good.
Ever consider your modifcations to your Boxster may have contributed to your failure?

What modifications? The only non-factory modification I have is secondary cat-bypass pipes. If you are suggesting cat bypass pipes would be a contributing factor toward an IMS failure I'd say you need to put down the crack pipe. It's bad for your health.

Now I know why you suffered an IMS failure - cause you are a jerk!!!

I have a 2003, 20100 miles and just did the LN Engineering install. The old IMS bearing was fine, showing no signs of wear. I did the install as a preventative measure.
Good day...

I have yet to see an extracted bearing that did not have some signs of wear after being disassembled and reviewed.. How deep did you look prior to coming to this conclusion?

Local IMS
This IMS issue seems way too common to ignore in my opinion. Just bought a 2001 with 34K miles and can't deal with the idea of having to pull and find a replacement engine!! The lady I bought it from bought a 2003 with similar miles; hers just blew up!!!!!
These are well engineered race cars......but ooops, sometimes an engineer makes a bad call and hopes the problem goes away....apparently it hasn't.
I gues I'm in the upgrade piece of mind camp......so I can spend more of my time DRIVING!!!

IMS Failure and Class Action lawsuit
I had a failure of the IMS last year in my 2003 Boxster S. I was ticked that Porsche said, "sorry, but not our issue". I found a law firm in CA that was pursuing a class action suit and just heard that they couldn't find enough failures with "in Warranty" cars to pursue a class action suit. I did put in a used engine and an after market bearing...all is back on the track and running well. Maybe, one day, Porsche will step up, but I will be in a C4 by then. :ah:

How many miles until you had a failure; my friends failed at 23K on her 2005 base model? After the IMS upgrade my bearing was ok.....but after pulling the seals didn't see a lot of grease in there...more a mixture of residual grease and oil. Think it was just a matter of time. If I ever own another one of these engine types I figure its the cost of ownership, and should be considered as part of the purchase... Porsche however has lost some luster with me...

IMS Failure on 2001 Boxster S
Yep won the Porsche Lottery, (failure of the IMS) although I caught it before the motor grenaded. My oil filter is showing lots of metal flakes and the oil has a metallic sheen so I have found a replacement 3.2 that will be going in soon with a oil feed line to fix this issue for the future.
Anyone interested in a 2001 Boxster S 3.2 motor that needs a rebuild?

I already have one that I have rebuilt. It now has 3.6 Liters & it puts out 300 H.P.
It's for sale here on the forum.

I thought the fact that I put a smiley face on my original comment would ensure folks knew it was a joke. I guess porsche666 didn't see it that way. I'd hate to think my IMS failed because I'm a jerk.......we'll need to add that one to the pile though along with the oil used, how hard the car was driven, how many miles it has, etc. Beyond a somewhat bad design with a weak sealed bearing by Porsche I supposed it's as good a theory as anything else.

Having read thousands of posts on the IMS and having sold any number of Boxsters over the years, my opinion is this:
Clearly Porsche had (or has) a design issue that they did not want to confront.
Sadly, many buyers have had to contend with the consequences of that decision.
Hey, I could be wrong.

Because most of them, by far, are not worth the paper they are written on...............everything is covered, right up until you file a claim...........

IMS victims please complain to NHTSA
My apologies if you’ve seen this posting in other forums. I’m trying to raise awareness of this subject.
I have an 04 Boxster that had confirmed IMS failure last week at 58K miles. Dealer employees, including service managers, have admitted to me that they have a significant number of IMS failures in this engine, and didn’t deny that it should have been a recall. I didn’t know of this defect until it (probably) happened to me, and feel angry that Porsche sold me a car without revealing a fatal design flaw (sealed bearing with seal that fails in normal use, then relying on inadequate lubrication from crankcase oil splash).
When I called Porsche (1-800 Porsche), I was told there was no recall for the IMS defect because “the government orders recalls and they didn’t order a recall” for the IMS issue. Recalls are triggered by complaints to the NHTSA – not very many complaints, no recall. NHTSA complaints and investigations can be researched at their website: http://www.safercar.gov/Vehicle+Owners . Between MY 2000 and 2005 there were only 6 IMS failures reported with std or S Boxsters. Brief internet searches reveal that the actual failure rate is certainly much higher than these numbers would suggest. Complaints can easily be filed at the NHTSA website. If everyone with IMS failures went to the NHTSA website and filed a complaint, perhaps an investigation and thus a recall might be triggered. I’m not sure if a recall could be ordered for cars this old, but at least the relevant government agency should adequately notified. If the government took action, Porsche would be forced to respond.

Wow, all these people that have had IMS failures simply have bad Karma. Porsche will be so relieved to know that the design of the bearing had nothing to do with it. This should save Porsche a ton of $$ on warranty and goodwill repairs!

Everyone knows that Porsche owners are jerks and this is karma's way of evening up the score. If you have not trodden on the poor to get your precious Porsche then the IMS will be fine but if you did trample the less fortunate then you may even have multiple engine failures.
Is it too late to repent?

Karma, huh? Your other posts certainly seem to ignore it:
" just bought my 1st 986, I am 70 Years old. It is stick shift. Hate it that the steering wheel does not tilt; makes it very hard to get leg (knee) under steering wheel and foot past clutch when getting into the car. Any suggestions?"
porsche666's response:
"Yes..... trade it in on a Cadillac. They have more room for a wheelchair."
Replying to jhandy's question regarding his car dying on the road:
"Aren't you a surgeon in Texas? Surely you can afford to buy a new car?"'t
porsche666's response at the top of this page:
"Now I know why you suffered an IMS failure - cause you are a jerk!!!"
Nice Karma ratio for only 8 posts.
