The engine sounds strong, if that counts for anything, but I've only put about 30 miles on the car, so it may be too early to tell. I'm too cheap to buy the Carfax report - may splurge for the Blackstone Oil Analysis test later in the year when it's due for an oil / filter change. This car is way out of my league in every sense, but what an awesome car.
You've had it a few weeks and only put 30 miles on it?

Yeah! I've noticed that you don't see too many Porsches out during the winter, and I don't want to subject it to rain and snow and salt and whatnot.

Another issue - it has what's called a "Muffler delete" system installed on it, and the ****er is LOUD! It's really not my style - I love the sound of the engine, but I'm not a big fan of people who make everyone around them share their liking for loud cars - don't want to be one of them. I have the old mufflers and plan to put them back in as soon as we get a couple warm days. -

02 C4S that just got its engine pulled after 52000 km / 32300 mls
IMS is clearly leaking, car was driven 10000 km / 6200 mls in the last 6 months, how far you guys think total failure was away?

What's the condition of the bearing? Any metal in the oil or oil filter?

Slight lateral play on bearing, no particles in oil or oil filter.

I haven't checked in here in quite a few years. Back in the day, it was all about the RMS.

A couple questions (I watched the PCA & Jake's vids ): It seems the failure rate is higher for a car like mine, single bearing, sometimes sits for months. I do drive it hard when I drive it, coming from an air-cooled 911.

How worried should I be? Should I drop the $$ now and get it done? When does the clutch typically go on these cars? It seems a lot of people wait until the clutch needs replacing. How much should I expect to pay to get it done? How much if it's done w/the clutch? Is there a shop in the Seattle area (preferably north) that does these?

Anyone sell insurance to covert this? I heard there was a class action suit. Anything come of this? I bought the car new.

Reading all these threads has me a little scared to drive the car when I was just starting to enjoy it again.
I've called Squire's in Bellevue for quotes and I will say James who typically answers was amazing over the phone. Worth a call if you're not too much farther north. My 996 is in the shop at the dealer's expense but when I get it back it's going to Squires.

Hello and thank you to all who have contributed to here for us noobs to the Porsche family. I have recently bought a 2001 carerra 4 with 116k. Bought the Carfax but no signs of any major work on the car. My brother is a certified Porsche tech and is fearful that the IMS has not been done yet. I knew the IMS issue going in but is there any way to inspect to determine if done or not? Also with the amount of miles would stock clutch and IMS last this long. Car is totally stock and very clean to boot.

Hi Guys,
I bought a 996 C4 Feb/2001 with 160.000km three month ago. The car runs very fine no noises etc.
But I┤m afraid about the IMS, so I┤ve spoken with Charles Navarro to give me an address at Germany.
The bearing of LN Engineering was installed two weeks ago by a shop at the Netherlands (because there was no shop in Germany with bearings from LN Engineering).

In my car was a double bearing installed. Looks good and no noises after 160.000km. The bearing was full of oil (not anymore grease in it).
See the pictures of the old one (closed and opened):

opened without Clip

Charles, thanks for the support.
