Hi Tim,
Unfortunately Mileage unknown on this engine , no smell other than normal engine oil,bearing came out with a loud snap at first (release of lock ring?) then ease out under light puller pressure,but no oil in tube to speak of, my 1st estimate of 1/4 oz is off when I turned tube over to pour out only a few drops came out. The bearing inners were wet with oil but how would it stay lubricated over heat and time? , IMO after seeing a sealed bearing both ends I was at least expecting to see a hi temp grease inside
