ive been chasing a mysterious oil leak in my 200sx (ga16de) for a couple weeks now.. i have oil all over the bottom pass. side of my motor under the car and splattered up on the back bumper. it hasnt been alot.. i go through a quart about every 2 weeks er so. but i havent been able to figure out where its coming from so i have been on a divide and conquer strategy. i changed my vc gasket, my oil pan gasket and pcv gasket. they all needed to be changed but im still leaking oil. i was about to break down and degrease the entire motor so i could figure out where it was coming from. but when i was changing my air filter i noticed oil dripping from my intake. so now im thinking it could be my valves but im not sure. i also have and engine light that came on cuz i have a small leak in my evap somewhere and ive been noticing a slight drop in throttle response and loss of power especially in 3rd and 4th gears. not sure if they are all connected but anyone have any ideas?

Too much crankcase pressure is forcing oil into the intake through the PCV (Positive crankcase ventilation) system. Change your PCV valve and related filters. I would start there...

how can i tell if the pcv valve is bad? it looks clean but it does seem like it could be one of my problems..
also another wierd problem, i got a engine light triggered and its giving me a code for a small leak in my evap system. but ive been switching out my air filter lately ( went from a box to a cone filter then back to the box with a K&N air filter) and eveytime i unplug my map sensor for any length of time, the light goes off.. coincidence or is there something there i should look into?
