Can someone clue me in as to where is the PCV valve located on a 2004 RX330. A photo would be nice? Thanks

 

maybe this will help https://us.lexusownersclub.com/forum...diy-with-pics/

 

Thank you, however, that engine on the 2006 RX400 does not look familiar. Does the 2004 RX330 even have one??? I only see a breather hose connecting from the crankcase to where the MAF sensor housing is located.

 

RX400h has 3.3l ehgine (RX330 + hybrid system)

 

PS: Is it yours?

 

It's on the rear valve cover passenger side and a real pain to get at.
Bent needle nose pliers was my friend but still cut my fingers up getting back in there to get clips off.

 

Thank you, your diagram solved the mystery. I've been barking up the wrong tree with 12262 hose!

 

Yikes! Thanks so much.

 

toughest bit of maintenance I have done on my wife's 2004 RX330. You must pull the intake off. Not a bad thing, if you want to clean the intake. Putting it back on was the worst part. The two bolts in back are a real challenge. You must do the left one first, and ONLY start the threads. Then, start the right bolt and go from there. Small hands make a big difference. Trying to hold the intake up while doing all that was the challenge.

 

inded it is a royal pita!! discovered this first hand when having help doing the rear plugs on my rx350.

 

Maybe my 2004 RX is different, but thankfully, I didn't have to remove the intake.
I was able to remove the cover over the power steering fluid/ABS area and get to it -- albeit, it was tight.
I changed it out because it was original and I had it out, but the valve seemed okay at that mileage (200k at the time).

 

That's where mine is too on 2004 RX330.

I ordered a new PCV hose too shown in pic above and getting the back clip behind the manifold to replace the hose was almost impossible for me but to just remove the PCV with hose clip maybe only minor hand cuts in your future lol

 

i just hope i dont have to replace mine anytime soon as i dont think i would be able to get to it myself because of where it is.
