Hello, back in a starlet after selling my old GT 7 years ago. I have bought another GT and in the process of a full engine rebuild. I have found some specs online for the main crank journal bearings but I'm a bit confused. Main journal oil clearance: STD = 0.016-0.049mm U/S 0.25 = 0.017-0.061mm Limit = 0.08mm I have a polished crank with new std size ACL main bearings measuring 0.050mm using a plastigauge. Are these still in spec? Thanks
Well from what I have read they are out of spec but I dont understand the 0.08mm limit bit? Yes more or less across all 5 are 0.050
Limit is when you need to regrind the crank. You will be fine. Make sure you use the correct oil for your climate. I use Shell Helix HX3
