Greasing a thrust bearing?

[Chris KC]

Firstly Roger, I very rarely oil the clutch thrust bearing; and then only very little, and with a heavy-ish oil. Then whatever might drip out quickly escapes through the girt big drain hole at the bottom of the bell housing. Result - no oil on clutch. (n.b. oil escaping from the rear main bearing is surely a much bigger issue here!)

I've never tried it, but as grease is more inclined to hang around, I should have thought it would increase the risk of contamination rather than reduce it.
