2007 Cummins ism issues

[race7820000]

I'm having problems with the turbo I think? I've always had a slight cough and black smoke out the exhaust if you lugged it. Wouldn't do it all the time. Also I thought to myself that you can here the turbo alot at idle through the exhaust pipe.

Anyways, the motor has gotten rougher almost like it's missing.

Now when you start it there is sounds of air coming from the turbo area, like it's building to much pressure.

If you put a wrench on the actuator arm and move it up The chuffin noise goes away and you can here the turbo, motor seems to run better when I do that but still has a "miss" to it but the build up of air goes away.

You can barely drive it, it feels your driving a car with bad plug wires lol.

There is no check engine lights on. Also I don't know if this is related but the engine oil dipsit is the style you turn to get tight. It has blown the dipstick out 3 time in last week

Thanks for the help[/b]
