i have difficulty with the logic of the statement "the damage was caused by roller skid" & "lubricant to good" to me these two statements don't fit together. one would think if the rollers skid because the oil is to good that would indicate a lack of friction between the rollers and the other components. no friction means no metal to metal contact which is an essential component leading to early failure. [apart from the introduction of an abrasive or corrosive material.] can anyone fault my reasoning? cheers wally..... ps on the subject of hygroscopic oil anyone who has had water in their engine oil [eg blown head gasket] would eventually witness oil emulsifying wth the water.
