• The same high-pressure pump cover is used. • Since the ICP sensor has been relocated to the right bank high-pressure rail, a brass plug will replace the ICP                 sensor.

• The ICP sensor is installed over the gasket. • The ICP sensor can be removed and installed without the removal of the valve cover. • After torquing the ICP sensor to specification, the valve cover gasket and valve cover can be installed over the               sensor.

• The ICP sensor has a new gasket. • The purpose of the ICP gasket is to seal the valve cover to the high-pressure rail and prevent the release of                     crankcase vapors or splash oil. • NOTE: It is important to apply a thin layer of… Read More »

• The front port plug is located towards the front of the high-pressure oil rail. • The rail was designed to be universal for both sides of the engine. One side of the high-pressure rail must be                 blocked off when not being used with the stand pipe. •… Read More »

• The rear supply-port plug is located towards the rear of engine on the high-pressure rail. It’s purpose is to allow high-pressure oil to flow into the high-pressure rail. • During engine operation, a small gap remains between the rear supply-port plug and the stand pipe. The force of         the hydraulic pressure… Read More »

• There are two new high-pressure oil rail plugs introduced with the redesign of the rail. • The rear supply-port plug (on the right) allows high-pressure oil to flow into the high- pressure rail. • The same high-pressure oil rail is used on both banks of the engine. As a result the front port plug… Read More »

• The high-pressure stand pipe is a two piece pipe that is sealed to the high-pressure rail and high-pressure branch         by o-rings. • The stand pipe is installed after the new wavy high-pressure oil rail has been installed and torqued to specification. • The stand pipe has a check valve inside to… Read More »

• The wavy high-pressure oil rail has special AWA (Acoustic Wave Attenuation) features to dampen hydraulic noises. • The wavy high-pressure rail uses two AWA fittings, a large one and a small one. The AWA fittings are placed in the     center of the rail. The smaller AWA fitting is placed in the wavy portion… Read More »

• The high-pressure rail has been redesigned to reduce noise through the high-pressure oil system. • The volume wavy high-pressure rail has increased from 15 cubic inches to 30 cubic inches. This reduces pressure         fall-off during injection and improved emissions and fuel economy. • NOTE: The larger volume oil rail will increase… Read More »

• The high-pressure oil rail has been redesigned to increase oil capacity and to reduce noise. • The stand pipes’ serviceability has been improved. • The ICP sensor has been relocated to the right valve cover/high-pressure rail. • DLC (Diamond Like Carbon) coated injectors.
