On the return trip from Colorado my 2001 Duramax started making knocking noise. Took it to the local GM dealer and had 2 and 4 injectors replaced. ( all 8 were replaced last September) Picked up truck on Tuesday and when driving home realized that knock is still present. At home on the driveway noticed smoke coming from crankcase vent hose and dipstick tube. Took truck back to the dealer today for more repairs.
Truck has 99000 miles.
Any idea what is the problem?
