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.

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
