I found antifreeze in the air duct from the air filter to the turbo, I am perplexed as to how it got there, The turbo is water cooled so I am thinking that the problem is somewhere in the turbo cooling system.
The cooling system does pressurize with air, and the coolant level does go down, there is no white smoke at all on startup or after warmup.
The engine runs perfect with no misses and a code scan revealed problems with a couple of glow plugs, cylinder balance reveals one injector, #2 with an abnormally high rading at around 5 but if the engine is up to operating temperatur and it is revved a couple times it comes down to a point that all cylindes are balanced.

Any ideas, other then my turbo cooling system or maybe the EGR cooler causing a problem..........

Thanks in advance...............

 

The only thing I've heard of as to why there would be anti freeze in the air filter is a head gasket but you said it's not over heating right? And is your coolant level going down at all?

 

What I found is that the head gaskets are blown at # 2 and 7 cylinders, because of the blown head gaskets it pressurized the cooling system, But the way the cooling system over flow is designed, it expells antifreeze towards the right fender right into the air intake at the air filter, this is rather dumb design..............
