High-torque engines often face failures in the parts that synchronize the Crankshafts and Camshafts to ensure correct timing. Failed hubs will send the engine into limp mode if you’re lucky, or cause valves to smash against pistons in a major engine failure. To avoid huge repair costs, also ensure that Cylinder Heads, gaskets, and the block are sealed and torqued with a new cylinder head bolt kit. Make sure oil reaches into internal passageways, and prevents advanced wear with Engine Oil Pumps in good working order.
