Over thousands of miles the end play between the crankshaft and the bearings increases. When the “fit” between the bearings and the crank is not perfect it lowers oil pressure and decreases lubricity. The less oil to the […]

https://snzhitech.com/vidz/cylinder%20block%20rebore%20&%20honing.mkv Cylinder Block Reboring & Honing Engines are subject to wear and stress from day-to-day driving, overheating and overloading.
