The inlet manifold is free of oil ? - any smell of fuel in the sump ? - how may hours has the engine ?- valve stem oil seals are a possibility - much crank case compression ? -if the injectors are over dosing the pots I would expect that the oil would become diluted with fuel. The injectors as to the best of my knowledge are a Bosch part you may get the repaired serviced at one of there outlets. Sorry if I sound negative but the injectors are the last part of the fuel chain if they are in trouble there is a strong possibility that the rest of the fuel system has equal wear.
We have some information on that engine and will try to help more if we can is that a Ec210B we are talking ?

The Engine has just under 4K hours. It’s a 2006 EC160BLC.
Im not sure about any oil in the sump. Seems to run fine except for the smoke.

I omitted to mention that if the Turbo was not making good pressure it will result in smoke under load if you have the possibility please check the pressure under load. Check the muffler is not choked as this will have a negative effect on the turbo performance.

No codes for crankshaft sensor on display. What do I need to look at specifically on the attached?

Uffex has provided really good info. How did you check the turbo? Just looking for oil or did you check the integrity of the shaft from the exhaust side to the intake side? Did you check your charged air cooler for cracks? How about the wastegate, if its equipped? Does it always smoke or just under snap throttle? Lots of things to peek at before fuel. Hope this helps you save a few bucks.
Yes checked the turbo from exhaust side and intake side as well. We took off piping and looked at everything. We checked 2 boots up top and they were ok but I have one more to check I found down low on the backside of the engine. Haven’t checked charge air cooler or wastegate (not sure where they are). It has smoked some a bluish smoke since I bought it (bought used about 200hrs ago). But within the last 50 hrs or so Noticed more black smoke and more of it. Still a little blue when first crank, and some smoke when running, but severest when under a load. Attaching a pic of it working recently.
See my reply to
please see my reply to funwithfuel. No one has been near the fuel system since I’ve had it (about 200hrs) other than changing fuel filters twice since had it.

I would recommend you check and or drain the charge air cooler of any oil. I would also check the injectors for correct orientation. If installed 180 degrees out they will spray outside the chamber in the piston and smoke badly. You could have blown an injector tip off which is not uncommon especially if you have had water in the fuel.
Does the turbo turn freely without contacting the compressor or turbine hosing?
Toy could always pull the injectors from the cylinder head and have them tested at a fuel injection shop. Much cheaper than a set of new injectors.

That's lack of boost. There should be a plug in the air horn feeding the intake. If you can, see if you can plug a gauge in there. You wanna see no less than 18-20 psi full throttle under load. If you are seeing less, your lacking boost.
