Rail coating, the factory rail Has no inner coating, it is polish Machined. A simple test will confirm this, Plug the 1st and 6th injector nozzles, and feed bung, add 2oz of water, Corrosion and rust will form in Hours,(If you Do this You will cause inner rail Damage) any type of inner coating would be subject to many types of detergents that are in additive’s and Fuel, this is why WIF is so critical for CRs and so damaging to the system when water has contaminate the fuel. If the coating was to not adhere correctly the entire fuel system and engine is at risk. Most manufacturers DO NOT RECOMMEND additive.
Bosch certainly would have the technology to create a inner coating that is not subject to water corrosion if it was necessary to protect the inner-rail, at the risk of catastrophic engine failure. Correct machining is the answer to eliminating ANY inner coatings (factory Rails DO NOT have). Coatings may flake off or decay and cause injector failure OR worst.
Inner coatings would Not last Long with wave phenomena that may occur in the system, It can be assumed and hard to explain the main behavior of the system, but reliable detailed information about the conditions in the rail may not be available …
So in conclusion Keep the water out, and the factory Inner Finish, All T&C modified Rails are Build on this Platform.
This is somewhat old and can be legally Posted , The ISB 5.9 CR system is some what different, But built on the same Platform ( Check out the relationship between Injector Pulse-with and Wave phenomena.
its somewhat deep but what great reading.WOW this system is so complex.
(Its Great to Be Here).
