Problems include
Excessive black smoke (has gotten worse over the last year or two)
Oil dipstick keeps coming out
Black Oily coating in engine compartment, passenger side, seems to be from the front.
Recently, gentle surging during acceleration
First, read the NOOB guide at the top of the page.
Which dipstick keeps popping out? Engine or transmission?
Its very common for the trans dipstick to keep popping out. IDK why. It just does that.
If its the engine oil dipstick, I'd say that it would take some extreme crankcase pressure to push it out. You probably also have a rear main seal leak too if thats the case.
The black oily coating is probably from your crankcase vent and boost hoses.
The crankcase vent tends to send a oily mist out and into the turbo inlet hose. The accumulated oil in the inlet hose and boost hoses will slowly deteriorate the hoses and the oil mist will eventually seep through.
The only real fix for this is to install a Provent and you will probably need new hoses too.
Also, don't fill the oil till its all the way at the full mark on the dipstick. The dipstick is marked wrong. Halfway between Add and Full is good.
The excessive black smoke and surging are probably related.
Could be because of any or all of the following:
bad MAP sensor
stuck open EGR valve
clogged fuel filter or other fuel supply problem (such as air in fuel)
How many miles are on your CRD?
Has the timing belt been replaced?
Most CRD owners have to do repairs themselves because good mechanics are hard to find.
