SOLVED: OM642 Engine Burning/Consuming Oil.

Update to Clarify: As the engine Revs up you can see Tons of oil is being blown out of the Turbo Intake side, AND NO THATS NOT GOOD. That amount coming out produced so much smoke you could see me from a mile away.

If your OM642 engine is consuming oil, and your getting a Check Engine Light with DPF Filter Error Codes, check the following in Order.

Also Remember your DPF & SCR will Remove the Smoke Produced from the Oil Burning. So you will NOT SEE Much/Any smoke coming out of your Tailpipe.

1st is Easy: Remove the Black Plastic Air Intake Manifold and Observe the PCV pipe that connects to the Air Intake Manifold.
Rev the Engine Slowly & hold for 30 Seconds at 2,000 rpm to see if Any Oil Exits the PCV hose. If a lot of oil exits then your Diaphragm is damaged.

Note: Do Not Leave anything Near the Turbo Inlet, or ELSE the Turbo will Suck it Up and proceed to Destroy itself.

2nd is Easy: Remove the Aluminum Charge Air Intercooler pipe. Rev the Engine slowly & hold for 30 Seconds at 2,000 rpm to see if Any Oil Exits the Intake Housing Outlet Side(as seen in Video).

3rd Kinda Hard: And likewise the Turbo Exhaust Side could be Passing Oil through its Seals As Well, but you will need to Remove the Short Turbo Exhaust pipe that is Attached Via V Band clamp. To see if any Fresh/Wet Oil is in the pipe.

4th Easy with the Software: Do a Cranking Compression Test using Mercedes Star Diagnosing Software. Here are my Results below.

Cylinder #1: 154 & 134 & 161
Cylinder #2: 182 & 140 & 163
Cylinder #3: 192 & 142 & 160
Cylinder #4: 168 & 146 & 160
Cylinder #5: 169 & 141 & 165
Cylinder #6: 160 & 138 & 159

On the 2nd test the battery voltage dropped to 11.9v
A battery charger was used to do the 3rd test.

5th Kinda Hard: If your Results are Lower than Mine then Consider a Mechanical Compression Test via 6mm Glow Plug hole to Verify that the Noted Cylinders are indeed out of Spec.
If the PSI Increases A lot by Squirting a little bit of oil down the Glow Plug hole then the problem is Worn Piston Rings...
