Airrik, yup, same thing applies to Tip models. The only difference is that you have tiptronic. From what I understand it's more of a hassle to remove a tiptronic trans than a manual one.

Just returned from the National PCA Parade where Tech Seminars and Forums were conducted by the Tech Committee, and the IMS/RMS subject was covered in detail (again). As a '99 Carrera owner, I worry about these issues a lot, of course. But the reality seems to be that (1) only a small % of the M96 engine series seem to be vulnerable, and (2) there is no pattern in re. usage, auto vs. 6 speed, or ??, that is predictive about a future failure...so long as you follow conservative oil change intervals...to include close inspection for early signs of leaks. Also, tear the oil filter apart at each oil change to check for tiny metal filings...another early sign of pending disaster. In the meantime, drive and enjoy as life is short.

a ZF Tip is a little more involved due to some additional linkage and lines and pry getting to the top bolts, but an M-B Tip is a whole other project; the engine needs to propped back or better yet, drop the engine and trans together to get to be able to disengage the trans from the block. if your lucky , your tech should just hit you up for another half hour to an hours worth for a ZF Tip since it involves reinstalling in the same manner.

You'll have to direct us to where this was stated; as to date, no one has ANY hard numbers on the rate. A lot of the published figures have been put out in cyberspace by people with an axe to grind and people who make money off the issue. One is from Spain and one is from Canada. One owns a Boxster the other a 996. The common thread for these two seems to be my car blew up, it's unfair, I want to sue, everyone give me evidence I can bring to a lawyer. No where do they reveal their maintenance practices - no where do they reveal their driving practices or conditions of use.

I think they believe that if they repeat these numbers enough (the 10%) they will become factual adding value or force to their cause. Problem is; all this does is drive down the resale prices of 996's which in my case last year helped me - but does a disservice to current owners wishing to sell. I've seen all sorts of warnings concerning older 911's, 993's for issues to look out for. Issues that don't look cheaper to fix then 996's. Why the drama over one model?

How many people pulling their IMS bearings as a preventative measure report that the bearing was in fact... ok when it is removed? From what I've read it seems to match the number who reported their bearings failed. There are no sure things in life. (Wait: Well there is ONE sure thing but I don't want to depress everyone.)

The chances of your marriage breaking down are far, far, greater then the chances that your 996's IMS will fail. Consumer tip: buy a 996 and don't get married - you'll save money. If your already married, diamonds every year cost way more then the annual maintenance on a 996. Just saying.

Hey Ed, the next Porsche I get will not have an IMS, which will mean one less "Question about IMS repalcement" thread!

I think 100% of the cars with a bad IMS have a 100% IMS failure rate

This explains why I don't worry about my IMS. I'm on my third wife.

Don't worry Tim, Porsche will 'engineer' another engine issue into your next IMS absent Porsche engine.

My dealership slipped 9 per 1200 out. I do not know if this is an actual number or not. But that is low.

And I've already began working on what it will be..
I certainly hope those timing chains are up the speeds they'll be seeing.

They already have. The 9A1 DFI engines have had issues with the HPFP (High Pressure Fuel Pumps) and reports of excessive sooting on tail pipes of some cars.
