Honda 17130-RCA-A02 PCV Valve Assembly

To inspect the PCV system, start the engine and allow it to warm up. Pinch off the crankcase ventilation hose and verify the PCV valve clicking sound. To replace, loosen hose clamps, disconnect hoses, unscrew PCV valve, remove and discard washer. On V6 models, remove PCV valve retaining bolt, remove and discard O-rings. Use new O-rings and tighten PCV valve securely.

Starting in 2003, newer Acura and Honda cars used a Positive Crankcase Ventilation (PCV) system that cuts down on hydrocarbons by taking gas fumes from the crankcase, bringing fresh air from the air intake into the crankcase, mixing it with the blow-by gases, and pulling it back into the engine through the PCV valve. A flexible tube runs from the air intake duct to the rear valve cap, making sure fresh air gets into the crankcaseliner where blow-by gases and fresh air mix to get pulled into the intake channel. Take off the engine cover, look for broken PCV system hoses, fire up the engine, and listen for a single click from the PCV valve when you squeeze the PCV hose. If you don't hear any noise when checking the PCV valve, look at the grommet and replace it if it's faulty. If not, just replace the valve itself. To replace parts in this system, open the engine cover, loosen the clamps, disconnect the fresh air intake hose, drain your coolant, disconnect the air intake duct, access the air inlet pipe, and reverse the process when finished. Unclip MAF sensor wires, loosen fixing clamps on both ends, and reconnect everything back in the same order, checking to refill cooling fluid when done. You can find the PCV valve in the front valve cover. Remove its bolt, throw away the O-rings, and put new ones in their place. Undo the clamps, take off the crankcase ventilation hose, and put it back the other way round.

The crankcase ventilation hose can be replaced by disconnecting it from the intake manifold and the PCV valve.

The mixture of fresh air and blow-by gases is drawn through the PCV valve to the intake manifold via intake manifold vacuum, effectively scavenging crankcase vapors.

Loosen the hose clamps at both ends of the fresh air inlet hose and the crankcase ventilation hose, disconnect them from the air intake duct and the intake manifold, unscrew the PCV valve, remove and discard the PCV valve washer, and install the new components. On V6 models, remove the PCV valve retaining bolt and remove the PCV valve, and remove and discard the old PCV valve O-rings. Be sure to use new O-rings and tighten the PCV valve securely.

YES IT COMES WITH 2 O-RINGS IM NOT SURE WHAT YOU MEAN BY POP IN GROMMETS
