EDIT: Of course after trying to pull it off for 15 minutes, 3 minutes after I post the thread I get it out. The trick was to use the flathead screwdriver and slowly pry it out from opposite sides, a 1\16th at a time and it'll slowly rise out. As confirmed, it's pretty gummed up and you need to shake it really hard to even hear the check valve move.
I cannot for the life of me get it out. But I can't pull it out with my hand strength. I can't pry it up with a flathead screw driver. I tried grabbing the end with a pair of plyers and leveraging the pliers against the oil filler cap and lifting rather hard but it didn't pop out. I'm literally watching the steel of the pliers deflect from the force I'm putting on this thing. I'm using quite a lot of strength to try and move it... I must be missing something. Any help would be appreciated.
I'm replacing it because 1) I'm already here replacing other hoses, and 2) I don't here the check valve rattling around, and 3) I want to see if it's clogged or not, 4) it's quite loose and you can see oil accumulation in the area (it's not the oil filler cap).
Lexls says to just grab it with pliers and lift it out, being careful not to damage the seal.
I use a heat gun, cook it enough where it's starting to get pliable. Might want to protect stuff around it with aluminum foil. Should always replace the grommet along with the valve.
You're right. It's super brittle, it's just disintegrating anywhere I try and grab it from the top.
I think it needs to be pulled up, form underneath. My first google searches tell me that people cut them in half, but this one is so small I don't see how I can get a blade in there. And, the bottom of the grommet is unsupported from behind so I don't even know how you can cut it. Other people are saying torch it to heat it up as well. Then shop vac + small tubing to get any pieces which crumbled into the valve covers.
Going to have a think\research tonight. No wonder this thing had tons of oil blowby, the old grommet is super loose and not creating a seal at ALL. The old PCV valve had a ton of play, and it looks like that was from the old grommet.
Fire is not the best idea in an engine bay heat gun gets plenty hot. If some of the rubber bits fall into the cover it's not a big deal they stay inside the baffle.
While I try to avoid ordering car parts from Amazon, it's just a freaking grommet. I'm guessing that the lack of Toyota packaging is because these grommets are provided in packs of +10 or so at the dealership. Plain packaging denotes a broken package.
My amazon review.
You might want to order a cam cover and bolt gaskets in case some of the old grommet falls inside.
Shoot some lube (WD-40, engine oil, ATF, whatever) in the area shown - get it between the valve and the grommet. Take a big, wide flat blade screwdriver or pry bar and insert it under the valve. Twist the tool - usually this is enough. If not, try twisting and prying at the same time. Put something (piece of wood) under the fulcrum. You may have to twist and pry in a few locations.
Yup! I got the valve out, the screwdriver method was the successful one. The grommet on the other hand... that I don't know.
I was doing my best to prevent it from falling into the covers. It gets close to dropping in whenever you mess with it, and I've already taken two chunks out of the top of the thing. Not good. We'll see how successful I am today.

Take an X-Acto blade (No. 11) and cut through the ID towards the outside OD.
I would just add that regular replacement of the PCV valve is good practice. Just because it rattles, doesn't mean it's doing the job. Oil will end up in the intake manifold. While this doesn't dump massive amounts of oil in the intake system, it still makes a mess.
Oil in intake manifold - poor PCV (mileage 93k)
Typical oily intake port after two Techron treatments spaced one oil change interval apart.
The next time you have the intake ducting removed, open the throttle body and peek inside.
I gave it another shot with a box cutter that I do have, which doesn't fit, and the flathead screwdriver but I don't like how close it's getting to pushing the grommet in. Just ordered one from Amazon overnight to arrive on Monday. I hate doing it, I try and do my best to avoid single-item orders like this, but it is what it is.
You're right. The grommet was leaking in the PCV valve and that area had insane oil buildup. I don't think the valve itself was leaking, but the seal between the valve and the grommet, and the grommet and the head certainly was. Here's what it looked like before I cleaned it. The PCV valve does rattle, but it's severely gummed up. It barely rattles one time before it "sticks" in the other direction. I have to shake it significantly harder than the new unit I bought, which rattles just by looking at it, bouncing back and forth.
I wonder if this is contributing to my car exhaust smelling "rich", especially on cold starts. I cant' say one way or another if there is any oil consumption (being burned) other than the smell, though it's closer to gasoline than oil.
As for the intake - I already have it off as this whole job was to replace a lot of the hoses and piping. Here's the best view I could get into it.

How do you remove the PCV Valve on the engine?
