Replacing turbo actuator cm2350

[Bengy88]

Ok I’m gonna try to weed through this, it looks kind of all over the place.
Oil leaking anywhere at the turbocharger isn’t a good thing, I don’t think the actuator will appreciate it when the oil seeps into it.

The terminating resistor will be in the def harness either near the tank or in the frame rail around the tank. If I’m remembering correctly the connector is blue. But if you have 60 ohms with key off and Vgt actuator plugged in then your terminating resistor is good.

It appears that you simply have a vgt actuator failure and possibly a turbo failure or just a leaky turbo as a result of it and could simply be over thinking it. (not that that’s a bad thing, these turbos and actuators are expensive). There are a few things we have all seen cause a turbo to leak oil such as air filters clogged, boost leaks, bad turbo positioning at idle, actuators not functioning properly, Hell even squirrels sticking their nuts in the hood ;) But I can’t say that I have ever seen these cause oil to leak at the arm. Someone else may have, and I’m not saying it isn’t possible but I’ve never seen it.
