VHT engine assembly lube adds the high performance edge to professional engine building and restoring. It drastically reduces friction on all moving metal parts with precision tolerances, including wrist pins, cams, lifters, gears, bearing and timing chains. VHT engine assembly lube can prevent permanent damage caused by seizing and galling, because it will cling tenaciously to all metal surfaces and will provide essential lubrication before the engine's oiling system can establish a permanent oil film. Sold each. 7 ounce aerosal.
