    yeah, I did that, too. Cheap autozone push-on crankcase filters work great.

    engines develope a lot of positive crankcase pressure when running. The higher performance engines create even more. At high RPM the oil gets vaporized into small molecules and float all over the inside of the engine in a gaseous state. The PCV valve has a vacuum hose going to the engine that draws that vaporized oil and pressure into the intake manifold and then burns it, remember that dirty intake manifold problem you had a while back, that was from the vapors. Instead of drawing those vapors into the intake you put small air filters on the locations where the large vacuum lines connect to the valve covers and vent the crankcase pressure to the atmosphere. In return you get a cleaner running engine and less oil consumption.

    i went from using a quart ever 2000 miles to no oil loss just by putting on breathers instead of using the pcv system.

    Greg is absolutely correct. That is the cheapest and easiest way to eliminate that problem. Or you could do a PCV catch can. A Catch Can just temporarily stores the oil. AMW makes a good product, but it is quite pricey...

    Cap the hose off at the manifold.
