Ran across the Outmotoring vendor announcement today about the fluid filled crank pulley for justa coopers.

Wondering, are the stock crank pulleys failing on a lot of the base coopers at higher mileage? I haven't run across too many posts of it for R50s, but did see a number of mentions of it for R53s.

Would appreciate thoughts anyone might have - should this be a preventative maintenance repair I should think about doing at some point, or is it just a wait until I'm stranded whenever or if ever that should be?
