My 2002 Carrera had the LN IMSB replacement at 36,000, miles prior to my purchase. My previous Porsche was a 2001 Boxster S which I purchased at 39,000 miles. During my Boxster ownership I read anything I could to educate myself about the potential problem. I changed the oil myself every 3-4 thousand miles using an OEM filter and I inspected the old filter for metal bits. I used Mobil 1 synthetic oil with that car. Prior to selling the car at 56,000 miles, I had my local shop replace the IMSB with the LN product, even though there was never a hint of visible material in the oil. This definitely helped the resale value. My advise, to those who are considering the purchase of a 996 is to have a PPI performed. If possible, have an oil analysis performed. If the car has not had the baring replaced, try to negotiate a lower price to offset the cost and have the RMS and clutch replaced at the same time. To me the 996 represents the best value available in Porsche ownership right now. These cars are lightweight, still very "analogue" with regard to overall control. The brakes are excellent and they are plenty fast. The headlights were pretty enough for the GT1. Just sayin. Cheers!

2001 Porsche 911 Carrera C4 Cobalt Blue
2001 Porsche 911 Carrera C4 in Cobalt Blue. 53,000 miles, no IMS failure, car built in November of 2000. Tiptronic, runs great, no plans to replace the IMS bearing. Porsche collector and mechanics advised me to leave it alone. I was asked..."Would you rather own a 911 with an engine built to Porsche specifications by German mechanics or have it taken apart by some local mechanic?" It's like cracking your chest open and having heart valve stints put in "just in case". Most of the IMS fear is generated by the companies selling the replacement bearing! By the way, get your flu shot or you could die.

A couple thousand dollars is cheap insurance if you ask me.
53K mile in 20 years/ why don't you drive your car more?

Do you have health insurance? ^^Tell that to anyone who's had their IMSB fail!

You know there are people that have had perfectly intact ims bearings replaced as a precaution only to have the replacement fail. It's truely a risk either way. I recently had the hood and bumper removed to be repainted because of chips and road rash. Now my power windows, sunroof and map lights don't work! Sometimes it's best to leave well enough alone. 😁 I appreciate your position though.

Never look back.

Service intervals have been clearly stated since inception. If bearings are taken past their service interval, time or mileage (whichever comes first), it's time to replace. Every bearing with a serial number of 10000 or earlier is past their service interval. Most every classic single row IMS Retrofits are all past due as well as we haven't made or sold any since July 2017, as it was superseded by the Single Row Pro when existing stock of the older kit was depleted.
There have been posts of failures of LN, EPS, Insaro, FVD, other bearings on Rennlist. Nothing mechanical last forever or is 100% fail proof. The IMS Solution is the closest thing to fail-safe and the only permanent fix.
