Mine had around 200K miles on the original double row.

 

2001 C4 cab 62k miles. Bought it new and it never saw the dealer or mechanic.Daily driver for 5 years then sold it. I changed the oil every 5K. Never even heard of the ims issue back then. Wish there was a way to find that car and see what happened to it. I now have a 2003 C4 cab 10,400 mile garage queen First thing I did was get the solution. REAL CHEAP INSURANCE! I put 7000 permagrin miles on it in 6 months and NEVER worry about the ims. I don't think I could have driven the car without that piece of mind. If the first car blew at least it was still under Porsche warrenty.
IF I would have known how much my 993 would have appreciated I would have kept it!

125,000 on my 1999

 

Actually, that was after the "IMS issue has been exaggerated by companies marketing solution" allegation. You didn't just merely ask a question, but you started off by stepping on the companies that have produced products that have helped keep our cars out of the landfills. Insulted? Me, nope. It takes whole lot more to get under my skin. I didn't spend the last 15+ years of my life developing products that would keep these motors from exploding. I truly hope you get many more years out of your car with the original bearing, but if it grenades going down the road, I hope you'll at least come back on Rennlist and admit you made a mistake. I did a poll back in Sep and basically out of 195 people that responded, only 22% are sticking with the original OEM bearing and only about 5% are replacing it with an OEM type bearing.

Cheers!

For the first few years of the m96 engine and g96 transmission, as with all new designs, there were no internal parts available and no authorization to do any internal repairs. If an engine or transmission was diagnoses as needing internal repair, the complete assembly was replaced and old one was returned for analysis. Many more engines were replaced due to RMS leaks in the early years (seal was redesigned 5-6 times) and AOS failure, IMSB failure was virtually non-existant unitll the single row IMSB's started to fail in spectacular fashion. These engines were replaced with the "AT" complete reman assembly's for a number of years until supply was getting low, then authorization was released to repair these engines with new shafts. No replacement bearing was available (there is an OEM "kit" now after 20 yrs..lol), no aftermarket bearing/kit was authorized..

As far as reputation goes, the reputation of the 996 failures even took down the 996 Turbo for a while. Most people didn't make the distinction between the M96 and the Mezger engines. We had 996 Turbo's traded in with 40k-50k miles for $29k -$30k (actual book value).. then the word started to get out that the Turbo was more robust and it's value started to climb back up while the Carrera kept downward.

 

Not forbidden but the subject has been beat to death! Many different opinions have been shared over and over again. Just go back and read the old IMSB threads over the past 15 years...

2004 C2 Cab here with ~ 60,000 miles. RMS was replaced under warranty early in the this car's life, probably due to leaking. Original IMSB, single row I think, in this '04 example. I plan to replace when needing a new clutch. /X3

 

The subject will never die.IMHO

I think you are an expert and that experts don't stop learning. Their desire to learn is what got them there to begin with.

 

Thank you for your amazing technical response to my question. I appreciate your time and efforts to our 996 community.

Personally, as a parting comment on this thread.... I think these 996 cars are amazing. Without a doubt, truly great Porsches! If you address the known issues, you'll have a car that will last a long time without serious problems and give you the biggest trill ride of your life, but if you ignore the advice of the knowledgeable, respected people on this forum, then you may find yourself on the side of the road waiting for a tow truck. That simple.

Cheers!

 

I have to agree about the greatness of the design and overall driving experience. It's pretty sublime compared to anything else of it's era, and it's a whole lot lighter than any contemporaries built today. It's why I plan on taking care of mine well and if something bad ever happens, it'll be time for a big upgrade.

 

'99 C2, original double-row bearing, 81,000 miles

 

My 99 C2 has 92k miles with the original bearing. A lot of those miles are track miles.

Commenting on the "value" tangent, the 996 came out a couple of years after the "cheap" entry level Boxster. The skin on the front end of the 996.1 is identical to the Boxster, including the headlights. I think this devalued the 911. The 996 was also mass produced and the first generation after the "classic" air cooled cars that were the core of Porsches DNA.

I think history will look back fondly on the models produced before the smaller displacement "turbo" cars produced since the 991.2. The 996.1 - 991.1 cars are smaller and lighter than each successive version. They are also less complicated. I think the 1999s will hold a special place as the last of the analog cars.

If I crash my 99 on the track, I will buy another 1999, even though I have the means to buy a more expensive version.
