Frequently Asked Questions
Do I need to measure clearances?
Yes. Set the main-bearing clearance to spec with Plastigauge during the rebuild.
How do I know the main bearings are worn?
A deep knock from the bottom end, low oil pressure, and metal in the oil point to worn mains. Confirm the clearances with Plastigauge during the rebuild.
How do I torque the main caps?
Torque the main caps in sequence to spec during the rebuild, after setting the clearance with Plastigauge.
