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
