Congratulations on getting the work done. Did you have a shop replace the bearing or was it a DIY? If you had a shop do the work, $1800 sounds like you got a great deal, assuming they did it right. Or was that just the cost for the solution, and not the labor, tool charges etc?

A Porsche mechanic told me yesterday that Porsche fixed the IMS issue in 2003 and depending upon the manufacture date of the car it may not have the bearing issue at all. This was the first I'd ever heard that. Is there any truth to this? I thought the issue was completely resolved in the 997.1.

Nothing was "fixed" in 2003.
I hope you don't allow this guy to work on your car. He is clearly less informed than most enthusiasts on these forums.

What I've understood to be consistent with the IMS failures is that they continued to plague the Porsche 911 until the 2009 (997.2) model.

Guys, I've got an'03 C2 6-speed w/ 105k miles on it, IMS/RMS replaced by previous owner and it's run perfectly in the last 1.5 years/6k miles of my ownership. I've noticed in the last thousand miles or so a slight engine knock (sometimes) on throttle tip-in (only pump shell premium fuel), along with a bit more oil consumption (~3/4 quart redline synthetic every 1k miles or so) and just this last weekend I heard a modest tick-tick-tick from the engine. My guess is the latter *may* be a lifter collapse, but not sure. I've spoken to a couple independent shops and they, understandably, can't confirm, but are not particularly concerned unless there were more pronounced symptoms. It's a 'weekend car' and driven spiritedly, but not dogged by any means. Any ideas?

Recent thread on the subject with good info: https://rennlist.com/forums/996-foru...king-help.html
While there are other things that can cause your symptoms, burning oil and ticking is commonly signs of scored cylinders. If that is the issue then you need the cylinders relined and new pistons, but there are also people that have successfully kept driving such cars for long periods of time after getting the diagnoses (but that's something that will be determined by your tolerance of risk after talking to your shop).

gnat, thanks for the advice.
I should have clarified: the car has not yet been in to be seen for these symptoms by a respected local shop -- they've so far offered a couple (of the typical) scenarios to the cause only. My next step is to get it in to be properly diagnosed in the flesh. Let's hope it's not scored cylinder(s)!

I currently have 65,000 miles on my 6-Speed, 2002 Carrera Cabriolet. For peace of mind I had the IMS changed at 48,000 miles. The car has been fantastic to own and drive for the past 14 years! The only real problem I've experienced is a couple of power window failures.
FWIW, another Porsche mechanic (not my own) mentioned that IMS failures were much more prevalent in Tip cars than manuals. Any truth to this?
Here's a couple of recent shots of my machine taken on CA Highway 1 in Pescadero. LOTS of top down days where I live!

2004 C2 3.6 tiptronic 55k km Right hand drive made for Australia - LN IMS Solution (sleeve bearing with its own oil feed) installed. I'm the 3rd owner, not tracked so I was told. So far do good

Mine is an '02 Cab with 37K miles. Bought it in August. I don't think the IMS bearing was touched and it was not mentioned in the transaction. So I'm gonna get it done before I put her away for the winter. My dealer, Paul Miller Porsche in Parsippany NJ wants to quote me on the LN bearing. I already have a quote on the IMS Solution from another Porsche specialty shop in the area. Is there a preference on which replacement bearing is the best one?
