How to maintain the Positive Crankcase Ventilation (PCV) system and PCV Valve on Toyota Sequoia?

The Positive Crankcase Ventilation (PCV) system reduces hydrocarbon emissions by circulating fresh air through the crankcase, mixing with blow-by gases, and drawing them into the intake manifold. It consists of a PCV valve and two hoses connecting the air filter housing, crankcase, and intake manifold. The PCV valve restricts flow during high vacuum for idle quality but allows excessive gases to flow back during abnormal conditions. The system may become less efficient over time due to oil residue build-up, leading to symptoms like leaking seals. Routine maintenance tasks like oil changes, air filter replacements, and spark plug replacements should include inspecting and cleaning the PCV hoses. Cracked or deteriorated hoses should be replaced. The PCV valve should be inspected, cleaned, or replaced if residue cannot be removed. Careful inspection of the hoses and valve is necessary before reinstallation.

Toyota Sequoia PCV Valve

The PCV Valve in Toyota Sequoia models is an important part that keeps emissions in check and, at the same time, boosts the vehicle performance. By recirculating bit exhaust products from the crankcase back into the engine combustion chambers, the PCV Valve enhances proper operation of the engine besides minimizing emission of hazardous substances. Depending on the intake manifold vacuum, the PCV Valve partially closes the passage at idle and fully opens when the engine is under load and therefore provides proper crankcase gas circulation without a direct influence on the engine. Moreover, the PCV Valve also has one other function of reducing the flame and can also help to build up compression to improve power. As it has been noted before, one should perform routine maintenance and inspection of the PCV Valve to avoid expensive services and achieve the prime performance of the car.
