Probably because they personally have not experienced the loss associated with one failing. When you have to face an owner and tell them that they are facing spending more on his or her dream car than it is actually worth because of a failure, you begin to understand the reality of an IMS failure.

I was an early adopter.....it's almost time to retro fit the dual row, retro fit if corrosive wear is an issue....Is it? Fresh Motul oil every winter storage; <5000km intervals. I am way under mileage wise.

IIRC one car in the facility undergoing the operation had a failed bearing come out while there...was able to play with failed bearings at the desk....it does happen.

The information I have for five chains: Driving style affects actuation of the vario cam solenoids which affects radial load the ims bearing. The load ramps up every time you drop below 3K as the solenoids phase the cams for low rpm operation. This increased cyclical load could contribute to other factors, precipitating a failure

Nothing like an IMS or oil post. Over 30 entries in 24 hours!

Although it has been discussed in countless threads the IMS issue is always a good read.

BTW, had mine done at ~84,000KM (~52,000M) along with clutch, flywheel and RMS. The original bearing came out 100% fine but doing the work was the best peace of mind money can buy.
