I have a 2002 with 85,000 miles and i am in the process of replacing the engine.

In a couple of weeks the boys at SCAN are hosting a tech night where they'll be replacing the IMS bearing in my first 996, which I sold a year or two ago to a very nice girl named Kate.

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.

There are plenty of owners not on RL that may have junked their 996's cuz of IMS failure and either traded it in or had it fixed.
I have a 2003 with 55k miles. I am looking for an actual count of model year and mileage of cars that have had a IMS failure. I am trying to seperate the myth from the facts. My car is off of warrenty in April and I have a couple of options.
1) extended warranty ($3,000-$5,000)
2) LN Engineering IMS Retrofit ($1,500)
3) It is not really a problem and stop worrying. (priceless)
4) IMS fails. (replace engine $10k-12k)
really? why? Why not set aside the paranoia and just enjoy your Porsche? Cars break sometimes, its inevitable..... Im going to do burnouts now.... Cheers
Are you the original owner? Has it been well maintained? Do you have a good indy? Can you fix some mechanical // electrical issues yourself?
Do you plan on keeping the car another 5 - 10 years? Are you willing to trade up to a newer P-car?
IMS failure count is subjective. There are plenty of owners not on RL that may have junked their 996's cuz of IMS failure and either traded it in or had it fixed. You can feel sorry for the RL owners that have had theirs fail..the numbers don't really matter. whether the numbers are high or low doesn't do squat, cuz your IMS failure is the one that will really count...
Don't wait for it to fail with another warranty...either spend $$$$$ & get a newer P-car or spend the $ and get the IMS retrofitted.
Talk to Charles at L&N. they serialize the IMS to your VIN. Ask him how long their IMS R should last, their guarantee or if they engineered it with a life expectancy... I didn't ask him ..I just asked a few questions of my indy and had it done in order to be proactive.
Do nothing....and save your $.
I talked to the parts guy at the dealer yesterday. My typical question "how many IMS failures have you seen?"
He responded but did not answer my question. He said "depends..how the car is driven and maintained and how often the oil change is performed."
I said "the IMS bearing is a sealed unit and shouldn't be in contace with the engine oil" in which he replied "well, it's not really the bearing but everything else in the engine..."
I chuckled and said "ok then."
What is this IMS failure you speak of? Is this something new?
Sometimes my wife has PMS, but it is not a failure, more like a guaranteed occurence. Also, I hope this IMS is not contagious, as I have had my flu shot, but not my IMS shot.

100,000 miles. No IMS or RMS failure yet. I did have to replace a faulty clutch. Darn thing went out after just 95,000 miles. Mechanic checked RMS and it was dry.
After tearing down 3 99 3.4 engines one with 103k and bearing was failed but not catastrophic yet one with 63k and bearing seals had gone, and one with 72k in perfect condition. All were OEM and never touched. Not very scientific or statistically valid but for what it's worth.
My Dealer parts guy showed me the shop drawing for the IMS assembly which did not show a bearing. Guess there isn't one so you can all stop worrying and just drive the damn thing.
What you want to do is PM a guy named LVDell.
He's got all the data already. He may be a little reluctant to share it though so whatever you do, don't take no for an answer.
He'll try to double talk statistics with you, but just keep explaining that your are conducting a "scientific" poll here and he'll come around.
By the way so far your poll is suggesting a 0% failure rate so I'd just leave it as it is.
Mine never failed too.
There is a guy on here that IMS failure crept and crept its way further into his mind till one day rumor has it he got rid of his porsche because of the fear. He still hangs around here as a ghost. Even his ghost is scared and drives a honda.
It's Wednesday and so far this week engines seem to be holding up fairly well.... We've only answered two IMS bearing failure calls thus far.
The record is 13 in one week! Percentages can't be accurately figured, because no one knows exactly how many cars were made, and of those cars how many have had replacement engines installed.
Thats the spirit!!
I will say my indy has 2 on the ground right now with IMS "issues" one is a rebuild with Jakes complete new engine, the other is going to swap for a junkyard motor and the indy is going to try and buy the take out motor from the owner, rebuild it and have it ready to swap into another car... sort of a ready built replacement
smart idea IMO
Actually I don't think Ivangene is familiar with the guys at SCAN. They're in my neighbourhood up here in North Vancouver.
In a couple of weeks the boys at SCAN are hosting a tech night where they'll be replacing the IMS bearing in my first 996, which I sold a year or two ago to a very nice girl named Kate.
Should be a good night out. Apparently doughnuts will be involved.
I have a 2002 with 85,000 miles and i am in the process of replacing the engine. IMS failure, and now engine is being replace. BRUTAL, how can this be so common and not be a design problem with nothing to warn or keep from happening.
Ah here we go again old IMS threads dug up. I suppose I will entertain.
Sorry to hear about your loss and hope it goes well for you with the replacement.
It is a known design problem and there are plenty of things to keep it from happening (regular oil changes, bearing inspections, ims bearing retrofit, ims guardian pre-emptive failure device).
In fact, Porsche eliminated the IMS bearing from their most recent engine. They also updated the bearing to a much larger one early in the 997's life before the complete elimination of the dreaded IMSB. Remanufacturered 996 engines also have the updated unservicable heaver duty bearing directly from Porsche. Clearly they are accepting that it is a problem. In some cases they will even help owners who's engines are out of warranty.
but seriously why don't we have a properly moderated IMS thread to document the problem and its outcome, which warranty paid for it or not, if porsche north america did something about it ect ect.
I think it would be nice to have a MODERATED thread on this. no bar talk, only fact.
or may be some people high up have paid off rennlist to keep it quiet
