Trying to replace the PCV valve on the 04 LX470, and it's so hard to remove it. Any tips?

Thanks in advance!

Mine was sticking as well. I pried up one side of it a little bit and dripped fresh engine oil in on it. A lot of people here have said theirs broke when removing it and I didn't want that to happen. The valve cover has engine oil in it, so it's fine to add some oil to it. Then I twisted the PCV and worked it back and forth until it came out.

A small piece did break off, but I retrieved it from the valve cover with one of these:

its held in pretty tight by the grommet. I think if you got a flathead and pried the grommet up it would loosen the grip on the PCV valve which you could then pull with pliers and reduce your risk of breaking off. Pulled mine, grommet was real crusty, so replaced both.

On my ‘03 LX it’s threaded in. Are you trying to pry it out or unscrew it?

98-02 pry, gently
03-07 unscrew

Thanks for the replies. Yes, on 04 it is screwed in.

Will try the engine oil trick. Also read somewhere to run engine 20 minutes before unscrew it.

Engine oil trick is for 98-02, which use a rubber grommet.
03-up are threaded on. Just muscle it off, counter clockwise. Factory uses red loctite, so it's very hard to turn.

Good to know.

Finally got it off by warming up the engine, and then push the wench with full body from the front of the car.
