"My coolant degas bottle is full of diesel fuel!"
As the 6.0L engine ages a new problem has started to appear more frequently - diesel fuel in the cooling system caused by a crack in one of the cylinder heads. This crack appears in an internal cooling system passage in one of the cylinder heads adjacent to an injector bore. Because fuel pressure is greater than cooling system pressure, diesel fuel migrates into the cooling system. See the illustrated pictures.
The traditional solution to this problem is, of course, to replace the cylinder head. This is a highly labor intense job which can easily cost as much as $4,000 or more.
This is a highly effective yet comparatively inexpensive solution to this problem which involves replacing the factory fuel injector sleeve with an extended sleeve which completely covers the cracked area and is cemented and sealed by a retaining compound. See the illustrated pictures.
Because the replacement injector sleeve reduces the effective diameter of the injector bore, it is necessary to replace the lower injector body with a redesigned part that will fit into the new injector sleeve. The book time to replace a single 6.0L injector is 1.6 hours. Once the leaking injector bore is identified, it should require less than 1 additional hour to complete the repair. No special skills are required. Unlike other methods of attempting to repair this problem, the results are not highly dependent on the skill of the installer. Anyone who is comfortable changing a 6.0L injector should be able to effectively complete this repair. We believe this repair method is superior to simply filling the crack with a sealing material, because the extended sleeve completely seals the cracked area so that even as the crack grows a leak should never reoccur.
