Holden colorado diesl smoke cominig out of oil cap when removed

SOURCE: bmw 320 diesle sport 53

sounds like a blown turbo.be carefull if you are using it as the engine can run on the oil and blow the engine up...if it starts revving you wont be able to stop it unless you stall it very quickly!!!!!!

I had the same problem. I changed the pcv valve and checked the hose. It still did the same thing. Then I checked the metal tubing that the hose connects to and found it was full of hardened gunk. I sprayed PB Blaster into the tube let it soak for awhile. Then took an old choke cable, put it on a drill and ran it into the tube like a drain snake. It took a while of doing this over and over but eventually got it cleared out. Now, no more oil all over the engine and hood compartment.

black smoke usually indicates to much fuel being delivered. If this is the case you need to correct it soon or you will damage the catalytic convertor. What year is the vehicle and how many miles on it? Is there a check engine light on? this info would help

It's most likely due to a clogged PCV valve or clogged/kinked PCV hose. I'll include a video showing PCV system operation.
I've seen this symptom many times on various engines, and the PCV valve was usually clogged/defective. A clogged PCV valve results in crankcase pressure build-up and fumes/oil exiting places on the engine that it shouldn't. A severely clogged PCV often makes oil leak/exit out of the dipstick, even with dipstick in place.
The good news is... if the PCV valve is clogged/defective, the "cure" is a very cheap fix. Usually less than $5.
PCV stands for Positive Crankcase Ventilation, btw.

But note that on some engines (those where the oil filler opening is directly above the rocker arms/valvetrain) it is normal to have a small amount of oil "spray" come out, as the rocker arms are dispersing oil thru their oil passage hole on top.

(Whenever posting vehicle questions, always please add the engine size/type. It helps in more accurate diagnosis.)
