Not that rough. I would say a 100rpm +- deviation before the repairs.

One thing I have noticed is the car is MUCH smoother now. idles solid, accelerates smoothly... could be the IMS tube empty or the dual mass... either way it is a great improvement.
I hear that all the time from IMS Solution owners... I never make the claim that its the reason for the smooth running, though I know what I've measured from test engines on the rough running index, and vibration meters with the same engine fitted with different bearings, back to back.

Sold my 2003 C4s with 120km on it all original IMS bearing. I am in the boat of preferring a stock car not one that has been refit.

Hope the new owner is as lucky with the car it was flawless for me.

2001 C4 Cab
63,395 miles took it to Indy and got the LN Retrofit and a bunch of other work done. Upon examination, Indy said there were no issues with the stock IMS bearing. Had to replace one scavenge pump as it was "gritty" upon inspection. There was ferrous metal in the oil filter which sent me down this road but that is the subject for another thread post and it apparently wan't RMS related.


Cheers,

Debo sends.

So, debris was found in the oil filter and oil, and the scavenge pump was gritty from debris, and the IMS was still Retrofitted? How did they justify this vehicle to be qualified for an IMS Retrofit?

2003 C4, 99000km - still running original bearings.

I do think I will get it replaced in the near future - I will just sleep better, one less thing to worry about.

I was recently quoted a price of $20K for a good used 996 motor. For that kind of money, I could buy the whole car.

What are you looking to spend for the used motor?

20k?? Im looking at motors from 5 to 7.5k with 2 month warranty. 50 to 80k miles.
I'll do my own labor.
I can order a motor freshly built from vertex for 10k

On this thread we've now seen a couple of these IMS bearing replacements into engines with metal particles.

You can even do a 3.8L 997S motor for under $20k from what I've seen. GL getting the car running again, tough luck.

Default 1999 C2

1999 C2 6-speed coupe 89,400 miles. A low option car, but it came with the Sport Chassis options (014, 030, etc). I am the third owner. Original owner was Michelin Research and Development. Car spent first 42,000 miles of its life with a roll cage and GT3 Euro seats. I am sure it was only driven to church on Sundays by a little old lady. Roll cage was removed before second owner bought it, but seats are still installed. As far as I can tell, it still has its original bearing. Second owner believes the clutch was replaced before he bought it, but he had no documentation. Looking under the car, it doesn't look like the engine has ever been removed. Engine number leads me to believe it is the original engine. Car was built March 1998 and engine is a low serial number 1998 build. It runs great and I really enjoy it.

Question:

My indy mechanic who has a lifetime of racing and mechanic experience with Porsches, told me that IMS failures are much more prevalent in cars with TipTronic trannies.

Is that true? If so, is it because there are more Porsches with Tip than Manual trannies?

Thoughts?

Bill

One can't make this connection... Period. The vast majority of these cars are manuals, and we see an qual percentage of manual and tiptronic engine failures based on production numbers. Gearbox doesn't matter at all.

Most of his lifetime of experience was probably spent with aircooled engines, and doesn't pertain to this topic. I say that, because my 20 years of aircooled experience doesn't help me at all with the M96 engines, or anything newer, either. Often aircooled experience creates hurdles for the person working with the M96 engine, I know, as I lived through the same thing many moons ago.

The technicians that attend my classes, and fight the hardest with the M96, are those with a lifetime of experience that gets in their way of learning, adapting, and evolving. I have had over 1400 attendees in my classes over the years, and can state this with great confidence.
