MM catch can installed
The lines are routed as follows: 10an oil cap fitting to 10an inlet on the can. PCV fitting to the fitting on the front of the intake(same as stock).
My fresh air line is now hooked to the black plastic hose that joins the rear of the valve covers together to the throttle body fitting. The old fresh air fitting is capped. He said this would be best so that fresh air would enter the back of the engine and pull from the front of the engine.
The filter on the can has a one way valve so it seals itself when the pcv is in use. If the engine has more crankcase pressure than the pcv can handle it blows off through the filter.
