The PCV Valve of GMC Sonoma is one of the important requirements that allows the management of emissions besides offering better performance of the vehicle's engine. The PCV Valve eliminates environmental pollution as well as the build-up of hazardous oil sludge through recycling the crankcase byproduct gases back into the engine's combustion chambers. Depending on the conditions of intake manifold vacuum, the PCV Valve limits the gas flow when the engine idles, thus avoiding lean of mixture, and, moreover, increases the flow rate of blow-by gases when the RPMs or the load is increased. Also, the PCV Valve pins down the chances of a fire by working as a flame arrester besides helping in regulating the perfect crankcase ventilation. Some of the problems related with the non functional PCV Valve; include contamination of the engine oil, oil leakage, and high fuel consumption amongst other damages that may require repairs.
