Last week while hauling a load my 2003 HO blew the #1 & #6 injectors, fuel flooded the crankcase and the turbo was ruined. There was tons of smoke, loss of power, and oil mixed with fuel everywhere under the truck.
The dealer replaced the injectors and turbo under warranty and said problem solved.
When I went to start the truck after having it "fixed" I could hear a knocking/clicking sound that wasn't there before.
I brought this to the service managers attention and he and the technician told me this was normal noise. They told me to drive it for a thousand miles and to come back for a valve adjustment.
I took the truck and drove it for 700 miles and just couldn't take hearing that sound anymore so I took it back to the dealer and pointed out to them that the noise was louder now, and that when touching the #1 & #6 injector lines, a pulse could be felt that coincides exactly with the knocking/clicking noise.
Power seems more or less normal.
The knocking/clicking sound is audible at idle and in all gears but is particularly prominent in 1st & 2nd gears.
The motor burned nearly a quart of oil in the 700 miles.
Dealer removed the valve cover and said the injector hold downs were tight.
They admit now there is more to the problem, but they don't seem to know what is causing the problem. They promised to get deeper into the motor on Monday.
I need to get back on the road and could use some wisdom from you fellas.
Any assistance or sage advice will be greatly appreciated.
What am I likely up against? Bad ECM? Scored pistons & cylinders?
