Toyota Tercel PCV Valve

The PCV Valve will reroute harmful engine crankcase fumes back to the engine where they can be burned in the cylinders. This essentially improves the cleanliness of the engine and reduces harmful emissions. This simple spring-loaded check device reacts to the intake manifold vacuum, which causes the flow to restrict under high idle suction. It then opens wider as the throttle and blow-by increase so that pressure remains balanced. The functions of the PCV Valve are designed to sweep moisture, fuel vapors, and acids out of the crankcase to prevent engine oil from sludging, help seal the piston rings, and prevent leaks. The inline one-way PCV Valve applied in the Toyota Tercel generations is attached to the valve cover opposite the fresh-air breather. Owners do not face any confusing style changes, just threaded or grommet fit. It also serves as a flame arrestor during backfire events. A quick shake or vacuum test will show that the valve still rattles freely if replacing the Tercel PCV Valve follows Toyota's normal service intervals. Otherwise, a new PCV Valve will restore smooth idle, steadier fuel economy, and cleaner exhaust. A 1980s Tercel and a 1990s Toyota of the same name share identical PCV Valve behavior and ease of maintenance, as the layout never changed.
