Abnormal Exhaust Noise on 02-05 Ford 6.0L Diesel Engines is a growing concern as these engines become older. As a result many of these units will fail inspections if this Exhaust Noise is not repaired.
Most installers have found out that the leak is between the manifold and the cylinder head. In addition this engine never did have a manifold gasket from the factory.
Exhaust Noise-02-05 Ford 6.0L Diesel Engines
Unique would be a good way to describe it, because now the engine was smaller. The stroke increased compared to the 7.3L. The bore decreased compared to the 7.3L. Not only was the engine smaller with 365 cubic inches, but the engine was totally revamped.
Some of the changes included,
- Different engine gear train
- Cylinder heads,
- HPOP oiling system
- Even more sensors and actuators
- EGR cooler and EGR valve
For most applications, improvements for any engine come from cylinder head modifications. Now for the 6.0L, the cylinder head would have four valves per cylinder. There are two intake valves each measuring 1.33” and two exhaust valves each measuring 1.10”. But, the valves were placed in the cylinder head in a “twisted” fashion with two separate intake runners per cylinder.
Hence, The reason for the “twisted” position was to help introduce swirl into the combustion chamber.
Remember, the combustion chamber is part of the piston bowl. The higher the port swirl is in the combustion chamber, the more efficiently diesel fuel will ignite. This also helps reduce the “knocking” sound that older diesel engines produced.
So the end result is a quieter engine that makes other noises come to life.
Consequently you will need to send the manifolds to your local Machine Shop to be resurfaced.
Now customers can buy manifold gaskets to solve this problem. So what are your choices ?
