Nissan 240SX PCV Valve
The function of the PCV Valve in Nissan 240SX facilitates rerouting a portion of burnt gases from the crankcase into combustion chambers. This rerouting process drives the engine for cleaner operations along with better efficiency. The PCV Valve uses intake manifold vacuum to regulate flow. The PCV Valve mainly stays closed during idle as the vacuum is high. The valve opens wider during higher RPM or load as the vacuum drops. This prevents the 240SX engine from running lean. This is done so the engine can accommodate increased blow-by. The PCV Valve is useful for routing the gases for reburning. It reduces harmful emissions, restricts the formation of oil sludge, and helps to keep oil and internal parts in good condition. Working as a natural flame arrester, it will not permit any back pressure to pass the intake and damage the crankcase. Because of the PCV Valve's function that allows proper ventilation, there may also be ring sealing. This may allow stable compression as well. This small spring-loaded unit is located opposite the crankcase breather for balanced circulation. It does its job automatically and usually only needs to be inspected occasionally over the life of a Nissan 240SX engine. Nissan reliability fits into the 240SX.

Nissan 240SX PCV Valve Parts Questions & Experts Answers
- Q: How to address the situation if the PCV valve fails to produce a hissing noise and strong vacuum when the ventilation hose is removed while the engine is running at idle on Nissan 240sx?A:The crankcase emission control equipment consists of a positive crankcase ventilation valve (PCV), a closed or open oil filler cap and hoses which is meant to contain the gases that are formed in the combustion chamber during engine operation. These gases, if not removed from the crankcase, can get mixed with and contaminate engine oil leading to sludge formation are recirculated back into the engine combustion chamber where they burn up without escaping into the air polluting it. The process of recycling involves clean filtered air being drawn into the crankcase, picking up the combustion gases, and carrying them through the PCV valve and intake manifold to be used in the combustion chamber. This is a very important vacuum controlled valve in this system because it controls how much of these gases are returned to the combustion chamber. When blocked, there will be gas leaks through weak oil seals or gaskets in an engine, thus promoting sludge formation and causing oil leakage. This information along with troubleshooting instructions apply to any engine that has PCV system. To check for any leaks on hoses or connections, examine them for signs of vacuum leakages and replace or tighten as required. With all engines running at idle, disconnect the vent hose from PCV valve. If functioning correctly, there will be a hissing sound as well as strong suction from your mouth when you remove vent hose from PCV valve with your car at idle speed. In order to check for proper operation of this valve you should remove it and then blow through both ends . Air should pass freely through from crank case side but hardly move from intake manifold side . Should this occur , replace such a valve immediately . To remove PCV valve loosen clamp on hose and take off from manifold-crankcase hose as well as intake manifold . Just do installation like removal except disconnecting all hoses then use compressed air to clean them replacing any hose that cannot be blown out by air.
