Pontiac Fiero PCV Valve
The PCV Valve in Pontiac Fiero car models is an important component which assists in the reduction of emissions and the improvement of the performance of the vehicle's engine. Through recycling of combustion byproduct gases from the crankcase back in to the engines combustion chamber the PCV Valve is helpful in reduction in environmental pollution and build up of oil sludge. Depending on the intake manifold vacuum conditions, the PCV valve controls the gas exchange while at the same time preventing interfer nationalism with engine operations. Besides, it has the function of the flame arrester, which protects the crankcase from possible damage under conditions, for instance, turbodiesel knocking or backfire. One must ensure to service PCV Valve to avoid side effects such as blocking of the engine oil, oil leakages, and high fuel consumption which may cause expensive damages.
Each OEM Pontiac Fiero PCV Valve we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
Pontiac Fiero PCV Valve Parts Questions & Experts Answers
- Q: How Does the Positive Crankcase Ventilation System Work and How Do You Check and Replace PCV Valve on Pontiac Fiero?A: The positive crankcase ventilation system helps to minimize the emission of hydrocarbons by drawing gases from the crankcase then circulating fresh air through the air cleaner then through the crankcase to mix with 'blow-by' gases before being directed by the PCV valve to the intake manifold. These consist of vacuum hoses and pcv valve, the function of which is to control the flow of gases depending on the engine speed as well as manifold vacuum. For maintenance of idle quality the PCV valve restricts flow when the intake manifold vacuum is high, and in an abnormal situation, it permits excess blow-by gases to flow back to the air cleaner for burning. Maintenance check of the PCV system is required because carbon and gunk can clog the valve and hoses resulting to rough idle, stalling, oil leakages, or sludge in the engines. To check vacuum look for the PCV valve filter which is found beneath the rocker arm cover; remove the hose and put your thumb over the end of the hose as the engine runs; a slight vacuum is expected. In case vacuum is low, then it requires more investigation, as, for example, a leaking valve or hose can lead to problems with performance. Shaking the PCV valve should produce a clicking sound; failure to which indicates it's time to replace it. The idiomatic expression 'if you want to fix something you should try breaking it' can be the case here: unlocking the valve and running the engine while attempting to draw suction will work as a diagnostic test: lack of vacuum will indicate a blockage in the hose or fitting. When replacing the PCV valve, the type chosen should match the engin requirement to prevent damage of the engine.
