Genuine Toyota 12204-62010 PCV Valve Sub-Assembly

I replaced my valve cover gasket because it was leaking oil & decided to replace the original OEM PCV valve since I was taking off the valve covers. The original OEM PCV has never been replaced at 280,567 miles. The valve was working good & still had a rattle when you shake it, except with the gunk buildup inside of it. I bought the rubber grommet & aftermarket PCV valve from a local auto parts store. They did not sell the OEM PCV valve, which was a terrible choice later on. After the install of the valve cover gasket & aftermarket PCV, I was happy that it was no longer leaking oil & did not think anything of the PCV valve since it was replaced as preventative care. 2 months pass & my 4runner doesn't seem to have as much response in acceleration, power, & lower gas mileage. A month later, started having idle issues & surging while driving. There was no check engine light & couldn't find any hidden codes during diagnostic scan. I decided to take out the aftermarket PCV valve & give it a shake. It did not have much of a rattle & not as smooth as before. I also checked the PCV valve vacuum hose, it was filled with crusted oil from all the years of buildup & the hose was very hard. I decided to purchase a new OEM PCV valve on Amazon & also recommend buying a new PCV rubber vacuum hose as well. The OEM PCV valve (pictured right) compared to the aftermarket is smaller & better manufacturered. The OEM PCV has a different bottom outlet & the rattle is smoother. It also fits the rubber grommet more snuggly & secure. After installing the new OEM PCV valve the acceleration, power, & idling is back to normal. The 4runner is running smooth as before & the gas mileage is good again. I definitely recommend the OEM PCV valve over the aftermarket one & hope this helps anyone with this issue.

Three things I learned from this install: 1. Don't use any plastic engine parts for any amount of leverage when trying to pull the old valve out. I cracked a vacuum tube mount off while doing so and had to gorilla glue it back together to complete this install. It took very little leveraged force to break it FYI. You can get to the PCV valve on the 3rd gen 4Runner without removing parts but there isn't much room to work with (hence the broken plastic). 2. The old grommet will completely crumble when you start to mess with it. I thought mine looked pretty good until I prodded it with my plyers. Buy a new grommet and plan to replace it doing with the PCV valve. Only buy the OEM Toyota version of it. 3. The old grommet will fall apart and will fall into what appears to be the top of the engine (it's actually not). I used a vacuum cleaner for suction and to pull the old grommet (which had mostly fallen inside the grommet hole) to the opening. I then used a pair of needle nose plyers to fetch it out, piece by piece. It can be done without taking the top of the engine apart. Stay calm. It's stressful. The valve I pulled out seemed to still be functional (150K miles) but it was gummed up some. This gave me some piece of mind. Other than that, the engine runs the same as it did before. This was a good purchase. Do it. Do it now.

This product is really genuine. I’m a DIY Dad and I am not a mechanic but decided to Replace the cheap old one on my 2002 Toyota 4runner because I noticed oil coming out everywhere and the engine of my car gets super hot. After installing this product, it makes a big difference and result is amazing. This product is easy to install.

Fits 2001 Toyota Tacoma Prerunner 6 cylinder. Been running for over 25 miles and no issues.

I was always taught that a PCV valve is easily tested by blowing through it. In one direction it passes the air freely - but in the other, it is blocked by the internal check-ball. Well when mine seemed to leak a bit in the supposed blocked direction, I bought a new one. It was the aftermarket brown plastic model from Adv Auto for $4. The main problem is - it acted the same out of the box as the one I was replacing. So I bought the Toyota OEM valve for $12 from Amazon. Guess what? Its base is metal. And it COMPLETELY seals in the one direction while passing freely in the other. Case solved. It may not make a huge night/day difference in the way my truck runs - but it works exactly as it should. And the metal base is much more solid than the cheesy plastic ones you see for less from the aftermarket sellers. I am not against using aftermarket replacements for some parts - but it is a good idea to be sure about the quality if you are considering it. All that glitters aint gold. And I recommend springing for a new rubber grommet when you replace your valve it it is old. Mine was old and brittle - and it broke off when I tried to remove it....such that I had to carefully (and painstakingly) fish out the pieces that fell in the valve cover port. The new rubber one fits easily and seals great - and prooved that even this small job is worth doing right.

¿Es la misma válvula como que si? La comparas en el dealer

What else is there to say, this was factory OEM, not just your "listed" OEM products. Buy here!

Easy to install and works as it should 👍

Perfect fit 97 4runner

Fit my 4runner 1999 limited, but they are kind of expensive compared to the dealer, maybe twice 🥲

Good product.
