93 s10 blazer air cleaner question.
 

how to you take the hose out of the valve cover that goes into the stock air box out. if i pull up on it, it wont come out. how can i get it out. i bought a k&n air filter. came with a big cone filter and a chrome pipe and a realy small cone filter that clamps onto the metal hose that use to go into the stock air box. but i want to put the cone directly into the valve cover. but i cant get the metal hose out of the valve cover. and another thing, where can i find new hose for the pcv valve hose. the hose that connects to the pcv valve and goes in ontop of the engine is not seating properly and is losing suction. thanks.
