Locate the air box on the top center of the engine towards the back. The PCV valve is located on the rear, underside of the air box. Although on some Accord models, a small air box bracket may be present, which will block view and access to the PCV valve plugged into the intake manifold. If by chance the bracket is there, then remove the retaining nuts, holding it to the air box side with the ratchet and a socket. Reach onto the intake manifold with a pair of needle nose pliers, and gently pull the PCV hose and valve out of the grommet of the intake manifold. Hope this helps!!!
You PCV will be located on the center, rear engine area. It is just below the intake manifold, between the block and intake manifold. The valve is housed in the vacuum hose that runs halfway into the engine.
Follow the large (3/8 in) PCV vacuum hose from the front of the intake manifold plenum (lg silver box with label PGM-FI ). It turns toward the pass. side then down between intake maifold tubes/runners to the PCV valve.
it should be located in the rear valve couver pushed into a rubber gromet with a hose running from it to the intake tube going to air box if not there then in the front valve couver same deal with a gromet and a hose running to the intake tube going to the air box. thats were 90 percent of ur pcv valves are located on most car trucks and suv's. im not real fimilyer with the 3.0 honda moter but i hope this helps
The general location mentioned is correct. However, unlike most PCV valves there is no hose connection to the valve. There is a single bolt that attachs the PCV valve to the valve cover. Loosen the bolt, then remove the PCV valve from the valve cover. It is inserted inside the valve cover. Very different from most PCV valves as far as attachment method to the valve cover.
The PCV valve can be located in several places. The most common location is in a rubber grommet in the valve cover. It can be installed in the middle of the hose connections, as well as installed directly in the intake manifold.
Once the PCV valve is located, make sure all the PCV system hoses are properly connected and that they have no breaks or cracks.
Remove the air cleaner and inspect the air and crankcase filters. Crankcase blowby can clog these with oil. Clean or replace such filters.
Oil in the air cleaner assembly indicates that the PCV valve or hoses are plugged.
Make sure you check these and replace the valve and clean the hoses and air cleaner assembly.
When the PCV valve and hose are in satisfactory condition and there is oil in the air cleaner assembly, perform a cylinder compression test to check for worn cylinders and piston rings.
