Black & White smoke and a knock?

Check for boost leaks, Do you have a boost gauge? Have you had a scan tool put on it? Just because theres no check engine light does not mean that theres no stored codes.

Does the truck run good?

Hate to say this but it might be a cracked injector body.

I did put a scan reader on and nothing.
It does run well.

I gave up and took it to the dealer today. $236 later all they could find was cloudy fuel. All the injectors everything checked out good. Put a new filter on it and still the same problem. Well the dealer said to run two clean tanks of fuel through it and if it is still doing the same thing bring it back. I got about 25 miles away when I was passing a truck on a hill in a passing lane. It was smoking but I stayed off the gas enough that it didn't let it knock when the check engine light came on and the power dropped off.

It is back at the dealer and they can keep it until it is fixed right.

If you have contaminated fuel the last thing you want to do is drive it out on a HPCR injected diesel. The tank needs to be drained & flushed. Then hope for the best because a dealer will not warranty injectors when you have contaminated fuel.

BINGO! You win the lady a stuffed giant Panda.

It took the dealer 2 1/2 days to find the bad injector. On the bench they all tested out good but when put back in and run up a hill it would throw a code for bad injector. He had to test them one at a time on the road with some kind of rig that required him to remove a bunch of stuff, hook the test rig up to an injector but the stuff back on and go run up a hill. Not only that but he had to test all 8 that way to find what one was different from the rest.

Now we are waiting for a new injector.

I had purchased the extended warranty when I git this truck 8 months ago and it has now paid off. $100 deductible is all in on the hook for.

Thats good news on the cheap injector replacment.

Change your oil & filter, the bad injector was dumping fuel in the crankcase.
