Hi,I dont drive my car very much, mainly just street legal/drag events. Normally I change the oil and filter after the season, (running E85) but I didnt do it last as I had used the car very little. I ran with it some events and thought I would pull the bearings to check and was surpriced how bad they looked... Both mains- and rodbearings did look strange. I am running Castrol Edge Titanium 5w40 with oem clearances (just with Plastigauge when I built the motors years ago) and ACL race bearings. I have now put in bearings with extra clearance and Castrol 10w60.
Could it be the Ethanol that have contanimated the oil/tearing the bearings? Or is it just wear from poor lubricating? I have a deeper oil pan/pickup with doors and have logged oil pressure when launching and was fine when I installed it some years ago. I havent checked lately if oil pressure is still fine while launching...
