How many miles interval do we need to replace this? Every 90k miles??

^Depends on the overall health of your motor; if its not burning or going through oil routinely, then it can go for quite a while. The PCV on my IS350 that I swapped out at ~60k miles was perfectly fine and still operating fine. If the thing wasn't but $10 to replace, I would have reinstalled it and waited till further down the road! LOL

I just went to the dealer for an oil change at 30K miles and the service adviser told me that replacing the PCV valve is part of the 30K service.... Can anyone verify is this is true? after all ive read on this forum, im concluding that it isnt part of the 30k service. he told me also about the oil change, engine air filter change, cabin air filter change, and the PCV valve change which is going to cost me $120.... thanks in advance!

The PCV valve is definitely not part of the 30K mile service. They aren't a part of any scheduled maintenance, they're a "if it breaks, fix it" item, unless the car is old and you just want to do it for good measure or something.

They don't fail anywhere remotely close to that fast. I mean they're cheap, but still.

so im trying to get into the space to take off the pcv valve but a standard socket 19mm (long) is angled when i try to loosen it. the top hits the intake manifold area (black plastic) . is there a special extension i should use? thank you

If I remember right, I used a deep-well socket to remove mine...after the line was disconnected.

is that type of socket narrow in the middle to the top?
thank you.

Due to the size of the PCV "nut", it'll be a smooth un-tapered socket. It'll be one of the bigger ones in this pic :

yeah thats the kind i tried. its hitting the black part. i also bought a small wrench but i cant get enough torque to loosen it.

So after 220,000 miles I FINALLY replaced the PCV valve. It still rattled as much as the new one!

^Just means you've got a very healthy motor. You bore scope vids confirm that.

Yoda tech here. I have yet to find a bad PCV on a 2GR or 2AR anything. 2AZ, 1MZ, 3MZ, etc, yes. Please post if you've found a bad one. I'd bet oil changes were skipped... lots of them.
