The diesel fuel system (see Figure 4-1) consists of the following components: • Low Pressure: Fuel tank, fuel (lift) pump, fuel filter or filters, fuel…

Build up of soot (carbon) or contamination of the air filter element is a result of exhaust gases emitted from the EGR valve. During normal…

During the service of 6.2L diesel cylinder heads, the observance of hairline cracks may be noted in the pre-chamber area. Cracks on the face of…

A burned out glow plug tip may bulge then break off and drop into the pre-chamber when the glow plug is removed. When this occurs…

See Figure 3-6. A design feature is the Ricardo Comet V pre-combustion chamber which has a spherical chamber which mixes the air and fuel by…

See Figure 3-5. A combination intake manifold and cross over is used. It is a splider air plenum type which allows it to be completely…

Air moves without restriction through the air cleaner and intake manifold (Figure 3-1 and 3-2) to the combustion chamber. The chamber is filled with air,…

If you encounter a diesel engine that exhibits excessive oil consumption, low compression or excessive blowby and you suspect stuck piston rings as the cause,…

To determine if the valves or rings are the cause of low compression, a test should be made to determine the cylinder compression pressure. When…

A low coolant indicator system is used in 6.2L applications. See Figure 2-60. This system consists of a: • Module • Probe • Low coolant…
