Injector condition some wet some dry?

I'll have test results to post tomorrow after pulling them to get then tested.
Ml350 bluetec 2010 om642 175k
Passenger side rear towards the firewall and the one in the middle were wet with oil.
All the rest were dry.

below is a photo of the dry one and a wet one.



I do have some white smoke with high revs. Even when coasting in a low gear under whatever vaccum a diesel produces.

Is it oil, of fuel?
I recall you made another topic wondering why your engine is using lot of oil.
That mighty be the answer?

Oil. And what's the answer? Something in the head in that cyclinder? I have no idea, hence my reaching out to the community. There arent vapors coming from the dipstick and the oil test was good, so not rings.

Leak valve covers would explain where your motor oil go, wouldn't it?
But the fluid color on the pictures looks to clean to me to be diesel oil, that's why I ask if that might be fuel?
Double check what exactly is it before trying to draw any conclusion.

There isnt a leak in the valve cover. No drops on the ground of oil either. (I dont have any undertrays installed either).

I'm happy to look for or investigate other options as well.
