Both cylinder heads have a rocker arm oiling manifold that cools and lubricates the valves and rocker arms.

The rear crankshaft seals have no sealing sleeves.

Both the crankshaft main and connecting rod bearings are color coded and a tangless design. The lower half of the crankshaft main bearings are a dark gray color while the upper half is a bright metal with a lubrication groove and a slot for the oil to flow through. The upper half of the connecting… Read More »

The following improvements have been made to the crankshaft. • Improved crank quality. • Fillet radius on each journal • Forged Modular Steel • Undercut rolled fillet radius • Fully lightened crankshaft pins • Two radiused counterweights • One piece rear flange: –– increase torque capabilities. –– improved sealing and balance. • Shrink fit assembled… Read More »

The pistons are oil cooled. A oil jet that bolts into the block sprays oil into a hole in the bottom of the piston. The oil flows through the top of the piston and exits from a hole in the other side of the piston.

The connecting rod is a fractured cap design.

The camshaft is driven by the crankshaft. The camshaft has one exhaust and one intake lobe per cylinder. The two exhaust valves are actuated by a single exhaust lobe and the two intake valves are actuated by a single intake lobe. The camshaft bearings are lubricated by the rear cam groove. This groove receives oil… Read More »

Gear Timing The camshaft and high pressure fuel pump are driven off the crankshaft. The timing gears are accessible by removing the front cover. The camshaft, crankshaft and high pressure fuel pump all need to be timed together. Note: The fuel pump is timed so that the fuel pump stroke happens at the same time… Read More »

Six bolts per cylinder seal the aluminum cylinder heads to the block. Each cylinder has two exhaust valves and two intake valves.
