Established in 1993, Guanfa Valve Manufacture Co., Ltd. is specialized China pcv valve manufacturer and distributor of valves, hoses, tubes and pipes. Our oem pcv valves are suitable for acid, alkali, water, steam, seawater, coal gas and natural gas. They are widely used in petroleum, chemical, paper making, fertilizer, brewing and metallurgy. The use of specialized software of Pro/E and CAD has shorted the P&D and trial manufacture cycle, and greatly improved the service life and dependability of products. Our high-quality products have been exported to the North Amercia, UK, USA, Germany, Italy, India, France, Australia, Japan.

The D0AZ valve has a larger nipple than the C9TE. It is the one listed for the 429 CJ application. The MPC lists this valve as the "EV50". "The purpose of the Positive Crankcase Ventilation (PCV) system is to remove these harmful gasses from the crankcase before damage occurs and combine them with the engine's normal incoming air/fuel charge."If your pcv-valve gets full with oil, your car will begin to build crank pressure, and may lead to blowby. If your pcv-valve is plugged, you will notice a world of difference after changing with this direct replacement.

Porsche used a PCV valve on some 1.7L and 2.0L D-Jetronic engines, mostly in the 1973 and 1974 models. Early 1.7L and late (1975 and 1976) 2.0L engines did not have a PCV valve, and the crankcase breather on the oil filler was connected to the air box. In cars equipped with the PCV valve, its purpose is to regulate the flow of blow-by gasses from the crankcase into the intake manifold, where they are re-burned in the cylinders. The design of this valve is critical for proper crankcase ventilation and idle performance. From the following reference: "During normal compression stroke, a small amount of gasses in the combustion chamber escapes past the piston. Approximately 70% of these "blow-by" gasses are unburned fuel (hydrocarbons) that can dilute and contaminate the engine oil, cause corrosion to critical parts, and contribute to sludge build up. At higher engine speeds, blow-by gasses increase crankcase pressure that can cause oil leakage from sealed engine surfaces."
