more questions on my 560 diesel... (engine ?'s)

I powerwashed it yesterday as it was greasy and dirty and I wanted to get all the crud off and use it awhile so I could find where all the leaks were coming from so i could get them fixed up. After I washed it yesterday I noticed that it started to drip oil out of the breather tube. It had not done this before in the several hours of operation, and when it started yesterday it is dripping a pretty good amount of oil. If left sit at the same spot for more than five minutes it will drip a puddle about 2-3 inches in diameter, and it is all coming from the blowbye tube, as I watched it drip.

My question is, is there something inside the engine that could be blocked and not letting the oil drain back into the crankcase? Instead pushing it out the breather tube? It is a diesel and it carries about 25-30 LBS oil pressure at idle. It is fairly snappy on throttle response and the exhaust smoke is nice and clear and no sooty evidence around the pipe other than the usual unburnt diesel soot you would normally find on any exhaust. The blowbye seems to be normal for a diesel and is not real heavy.

Just trying to give any info that may be relevant here. Anyone got any ideas as to where to start looking? Thanks for any help and if there is more you need to know to help me just let me know.
