Description

The MK-6107A is a comprehensive engine overhaul kit. It includes components like gasket sets (head, valve cover, oil pan), various engine bearings (main, rod, cam), valvetrain parts (timing chain, camshaft, lifters, push rods, rocker arms, valves, springs, seals), cast pistons with specific dimensions and design, premium moly piston rings, an oil pump assembly, and a full set of freeze plugs (brass and steel). It's designed for rebuilding, but notably, head bolts, connecting rods, and main bearings are generally separate.
