Thinking thicker = better lubrication, doesnt always work out right

Yeah, who knows if that was the cause but oiling plays a HUGE part in this obviosuly. For the record I have been running that oild for over 3 years and the motor has made over 400 whp for a year and a half. I have a good old 7 bolt 4g63 Evo IX, not a X.
It will be interesting to see the wear on other bearings once I have taken more apart.
