I have an Unorthodox Racing underdrive, lightweight pulley on my FS 2.0L -- How long till the bearings implode?
I had it installed during a t-belt change at around
83k miles back in 6/2001.
I'm currently at 227k miles. Idles smooth, runs/pulls very smooth, doesn't burn/leak oil -- I'm hoping to get 300k out of it.
edit: my pulley is shiny blue aluminum, maybe that helps
