How to check the PCV Valve on Ford Excursion?

To ensure efficient operation of the PCV system, clean hoses and check the PCV valve as stated in the service schedule. Determine where the PCV valve is located in gasoline engines by checking for a valve cover. Start the engine, disconnecting the hose from the cover and doing vacuum test. If you feel a vacuum, it means that your system is functioning properly. If not, check for vacuum in the hose. Replace the valve if there is only a vacuum in the hose and not at its head end or inlet. It should be changed if there is no vacuum in the hose at all. Reviewing for blocked or broken hoses should be carried out where no suction exists along with inside drain tube assembly. Examine grommet for damage replacing it if necessary. Using solvent to cleanse the pipe, uncover damage while assessing it for wear and tear before installing another one.

Ford Excursion PCV Valve

PCV Valve in the Ford Excursion Vehicle is one of the devices that can control emission and improved the performance of the vehicle's engine. The PCV Valve directs combustion byproduct gases of the Hank's crankcase back into the automobile's combustion chamber thereby not posing environmental polluting effects and it also avoids building up of oil sludge which is fatal to the automobile's engine. Deemed to function according to the conditions of intake manifold vacuum, the PCV Valve limits the passing of gases at idle to avoid lean running and on the other hand, lets through increased blow-by gases at higher RPMs or loads. PCV Valve also works as a flame arrester besides helping in ensuring the right airflow by ensuring that positive pressure in the crankcase never builds up. PCV Valve should be maintained frequently so that problems such as an engine oil contamination, oil leakage, and excessive fuel consumption can be solved at a minimal cost.
