SKF crank bearings.
Whoa finnaly found this thread again. Ive been doing some reasearch on cage material for bearings and I might have found a possible reason for why the black plastic cages were melting while the rollers were still intact. It seems use of an extreme pressure lubricant lowers the operating temps that a plastic cage can run it. Possibly as low as 215 degrees. A partial blocked radiator or siezed cooling fan could easily make this happen. There are a few types of plastic cages made for just this issue . The name of it is PEEK.

Ive been running Mobil 1 pretty much exlusively in the engine and Transynd in the tranny for many years with no issues on plastic parts. The skf bearings have also proven themselves . I wonder if the EP gear lube in the transmision can be atributed for cam chain guide wear I see in some engines I get in. The black plastic does look similar to the stock bearing cages?
