Crankcase Evacuation System
On my car I had a set of headers with the port in the right location and it even had a slight vacuum at the breather at idle . I they are not installed correctly they will not work . It just smoked a little , I dont run them any more because , I had to buy new headers and bought really nice ceramic coated headers and didnt want to mess them up , also those headers were on it when it was race only. Remember that GM cars with SAI and an air pump use exuast check valves . they to at idle have suction on them , this is because the check valve only allows flow in one direction so as the exhaust pulses this creates a vacuum. The trick set up is to get a Late model GM electric air pump and plumb it to the valve cover breathers , and this will really suck it down! But dont run it all the time because it will cause the rear main and front crank seal to leak and the oil will mess up the pump .
