Any ideas on how to clean the PCV?

I have smoke coming from the oil filler and dipstick

Anhyone?

I've been looking at that thing for a while. Info is scarce. The only thing gleaned from searches is that anyone who has taken the top off has found nothing and blocking seems to be a petrol issue. Getting it out looks tricky as the top screws are almost inaccessible and I can't work up the enthusiasm to pull the entire oil filter housing off - curiosity is a dangerous thing.

I'm not sure if this helps, but I came across this video on youtube the other day when looking for something else. Im not sure if the prinicples arethe same between petrol and diesel, but if not, have a search. Its quite a job from what ive seen. Not complicated, just long winded..

I have an idea that the crankcase pressure goes negative over 1500 rpm or something like that so at idle a bit of fumes is normal.

Hmm. My indy said there's a pressure build up in the sump pushing the dipstick out..possible breather blocked. They've been pretty good before. Also overfilled with oil. Not the rising oil level apparently!
