Q&A

Lyons24,

I'm sorry you are having an issue with your 6.0L. Yes, it's not usually a great idea to keep driving the vehicle with all that smoke. I suspect that you have a failed EGR cooler and failed engine oil cooler. This is extremely common, especially in cases where the coolant is not refreshed constantly or replaced regularly...which is true for most 6.0L's. They are really sensative to this.

You could also have cylinder head gasket issues, but this is less common, even though it's still possible.

The worst issue here is that you probably are getting coolant into your cylinders. If this is true, then you could lock the engine (hydro-lock - due to coolant in the cylinders), bend rods and damage components. Bearings do not like water / coolant either and can deteriorate.

You could also have a leaking injector (or two...or three...or eight...) dumping fuel into the cylinders. This would usually show up on the dipstick, though, as the oil level would increase.

In any case, get it to an expert 6.0L Diesel tech as soon as you can. And best of luck, happy holidays!
