• First, apply oil to the oil supply line o-ring. • Orient the supply line where it will be positioned once fully installed. • Press the supply line/o-ring into the cooler.
• Part way through the 2003 model year, the turbo oil supply line changed in design. • The early design was a quick-connect/disconnect style (left). The improved design (right) provides a larger o-ring seal and is held in place with a bolted down collar. • The new design improves the line’s long term… Read More »
• The GPCM bracket has been modified to accept the repositioning of the ICP Sensor. • An earlier GPCM bracket will not work on an updated 2004 MY engine.
• The FICM brackets are now composed of two bottom pieces and two smaller top pieces. The bottom brackets are pictured here. They slide over valve cover bolt studs as did the previous brackets. • The new brackets have larger vibration insulators at each valve cover mounting point.
• The water pump impeller diameter has increased in size to 100 mm from 90 mm. • The larger impeller will increase coolant flow through the engine which will offset higher heat rejection. • Note: Both water pumps have the same bolt pattern, but a different sealing area. As a result, the smaller water pump… Read More »
• Due to the design change of the piston, the glow plug has been made shorter by 1.2 mm. • NOTE: If the longer glow plugs are installed into an engine with updated pistons, glow plug to piston contact will result, ending in potential catostrophic engine failure.
• The combustion chamber on the piston has been modified. • This modification increases the efficiency of the combustion process, allowing the 6.0L engine to meet tighter emissions standards.
• The lobe separation angle, lobe lift, and duration have changed to improve combustion characteristics. • Changes have been made to the camshaft to increase the efficiency of the 6.0L engine, allowing it to meet tighter emissions standards. • It is not recommended that the updated 2004 MY camshaft be installed into… Read More »
• The six M8 bolts which were placed in the center of the upper oil pan have been eliminated. • Additional strength has been cast into the upper oil pan. • An upper oil pan which has bolt holes present should always be assembled with the six specified M8 bolts. Failure to do… Read More »
