serious black smoke
Hi all, I have a 2001 ram with 5.9l cummins. recently it has started to smoke heavily on acceleration or when climbing a hill. i checked for codes and there are none. I am suspecting that the wastegate is the problem.I put the park brake on and my wife presses the accelerator, and i cant see the wastegate actuator rod moving although i think i can hear the turbo spooling up.I dont have a boost gauge fitted. Any ideas of how to troubleshoot this problem, i am not very familiar with diesel engines.i suspect that the wastegate may have frozen , could i try to move the actuator arm with a small wrench.A little guidance would be really appreciated.
