PCV Replacement on Honda CIVIC/Del Sol D16Y8...the EASY way (SOLVED)

This video describes the easiest way to go about replacing a PCV valve on Honda Civic/Del Sol D16Y8 engine. The PCV valve is NOT in the typical place, so it is often overlooked in regular maintenance. This video demonstrates the easiest way to access the PCV and replace it. It is recommended that you do this while performing an oil change, as the oil filter does need to be removed to have ease of access.

Awesome! great video. I Have searched for weeks and have pretty much watched them all.. and this one is got to be the best showing how is done. Big thanks for sharing! 👍👍👍

Glad that it helped!

Nice job🤝🔥💯💪

How hard was it to get the PCV valve back in? Been having trouble getting the valve to actually go back into the grommet it sits in.

[@ScottyWrenches]

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.

[@Helloverlord]

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

[@relicrsps1621]

Awesome, im gonna try this soon. Theres oil in the intake manifold.

[@ScottyWrenches]

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

I just finally cleaned, sealed and replaced all the parts to the Breather Box! Grommet, O Ring, rubber tubes etc etc...
Car seems to be running much smoother.and better gas mileage it's a 95 Del Sol, Honda Civic.,.. The Breather box and parts have never been replaced, ever. What does this do for the car when you clean, seal and replace all the parts to the Breather box? Better Gas Mileage, more Horse Power?

[@ScottyWrenches]

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.

[@ketvaa]

are there 2 pcv valves?

[@ScottyWrenches]

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.

[@ketvaa]

@@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

[@ScottyWrenches]

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

[@VtecFrimzy]

What do that that holes do ?

[@ScottyWrenches]

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

[@Helloverlord]

I've had a D16W5 vtec in 2000 honda hrv, it was a struggle to pull that sucker out as all that space accessible on civics or desols, is populated at hrv bay with pipes, crossmembers and all other crap, this was not an easy job at all...btw part number is 17130-ph1-003

[@Helloverlord]

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.

[@ScottyWrenches]

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.

[@ScottyWrenches]

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

[@gorrioncico]

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.

[@Helloverlord]

@@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.
