Glad that it helped!

Easiest to do on your next oil change as the filter will already be out of the way!

Mike- PCV and breather box balance pressures from the crankcase (meaning below the pistons) and the head (the space above the pistons). This helps prevent blow-by of oil and reduces some of the inefficiency of overcoming pressure differentials. That is most likely why you see improved smoothness and MPG. When stuck or leaking vacuum, the PCV will also allow more air into the intake possible causing a too lean air-fuel mixture condition.

Once the hose is dropped back down in place (with PCV valve attached and clamped), I was able to simply line it up with the grommet and it slid in with little force. Make sure you have it centered...That might be what is holding you up. Otherwise, is the PCV the same diameter? If not, there is NO WAY it will fit.

If grommet is hardened (being for too long there) it's going to be hard one, try putting some grease onto valve end...

There is only one PCV valve. On this particular set-up, Honda placed it directly into the breather box on the back of the engine, which is why it is so often overlooked in maintenance.

@@ScottyWrenches found it when i took the whole system apart yesterday, on d15b7 engine the pcv valve goes in a rubber gasket mount thingy sitting right under the intakemanifold and then a tube goes from there directly to the breather box. A hell to screw apart

@@ketvaa the d15b7 has a different set up. My video shows the D16Y8. Glad you figured it out on yours!

@@ScottyWrenches What is part #2 in the diagram?

@@vinnyrusso1994 That's the PCV valve for the D16Y8. The other part listed (#6) is a PCV valve, but that's for the D15 engine (or maybe the B16A DOHC)

Not sure what you are asking. Please clarify so I can help you.

Another thing, as pcv is essentially one way valve, if it's too difficult to remove it, you could test it by blowing air from a hose intake end and it shouldn't get through, but if you suck it back it should, do it by using your lungs not a compressor.

I can only speak to the del sol D16Y8. I would imagine that the HRV is tougher with the braces and transfer case for the AWD, all put into a smaller front end. Thanks for the information. The part number does not cross reference for my vehicle (del sol). PS- replacing the grommet is a great idea if it's hardened. The hardened grommet could cause a vacuum leak.

That's one way to test it while in place!

Hello. Did you manage to change the PCV of the HRV? I need to change it since the section of pipe is crushed and I will have to do it from the ground, removing the oil filter...I cannot access it well below the intake. Tell me details or tricks to remove it please.

@@gorrioncico I did, barely. Best way is to use two modified flat screwdrivers to pry it, one goes through a hole between 2 i 3 intake other underneat, best to use another pair of hands, remove injectors and as much stuff around the intake to free space, good luck.
