pcv valve slugded up with light brown substance. (no milky oil)

What is your question?

oil cap was bouncing - so i changed the old pcv valve, which it and the hoses were clogged up was well, (oil cap stopped bouncing after) i cleaned everything out. the new one seemed to work great for about two days, the car drove great too. but the oil cap is bouncing again, car is laggy and unresponsive, gas mileage is way down, white smoke comes out of tailpipe only on startup along with a high idle until the car gets up to temperature.
