[QUOTE="machoheadgames, post: 429107, member: 18789"] Stock, no real need for anything else. On a 4.0, the front elbow needs to be free flowing and the rear elbow needs to have an orifice. If that is the case, and the hoses have no leaks, and engine is in good condition (minimal blowby), you won't have issues. No issues with mine whatsoever. Sometimes the engines will puke oil onto the air filter, on a 4.0 this happens when the orifice elbow gets clogged. Pressure forces oil up the front elbow and down to the airbox. On a 2.5, only one elbow is used, it's placed towards the rear, and it is hooked to the airbox. The line to the intake manifold is hooked to a threaded tube in the valve cover. When 2.5's puke oil onto the air filter, it is because the threaded tube got clogged and pressure forced oil up the rear elbow, and again, up and down into the air filter like a 4.0. [/QUOTE]
