PCV Valve Location
 

Wanting to change out my PCV valve on my 2015 RDX with the 3.5 engine. Have looked a numerous Youtube vids on the how to, but my valve isn't on the left side of the engine over near the dipstick. I grabbed a light and looked all around but can't seem to find where this sucker is hiding,,any help is help that's appreciated,,only one thing I know, it's not where the others are that are in the vids I've watched.

Did you remove the black plastic cover?

oh, cuz it's on the other side..

Yep,,I removed the cover and by the looks of where this gizzmo is attached, I have a funny feeling, it's not, in a place that's friendly. Thanks for the picture, I will look again tomorrow, and plan the attack.

^looks to be on the very top of the valve cover, remove the black plastic cover and you should see it above the oil cap

Yep ! That's exactly where it is. Appears I will have to remove the wire harness going to the coil packs and the air handling system going to the air filter to get to this. Hmmm Not a friendly place to put it, but that's where it is and how it is also
Thanks For the help,,got me pointed in the right direction. Wondering if this is the right parts 17130-RCA-A02 ?

yes! you are correct!

I used this website for the diagram;

Okay, part has arrived and have completed the procedure. I hadn't seen the video that I'm sharing when installing the pcv valve, but I searched for something to guide me after doing the job. LOL I had a little thing sticking in my mind when doing the work. There is a bearing
that goes between the valve and the bolt holding the valve to the block. There is a flange on the bearing , and I had forgotten if that flange on the bearing went under the valve and separated the valve from the block a bit , or the flange went over top of the valve and then the bolt . I finished the job and then started to wonder about it. I put the flange part between the block and the valve and afterwards had misgivings if the work was correct. I then started searching for a proper vid and came up with the one below. Thankfully I guessed right and
won't have to go back in again. The vid shows just about exactly what I did, by removing some of the wiring harness and such, so as to get to the little sucker. I have to add, when doing this job, be extra careful . my son has done this procedure many times, and he told me , that he hasn't gotten one of these parts out of the engine, with out it braking in half, and then resorting to find a die tap to thread into the remaining part of the valve and pulling it out that way. Guess after a lot of heat cycles , these things loose some strength.
Thanks again Justnspace,,ya got me on the right track

The PCV valve that was removed, was stopped up. There was no sound to it when trying to make it rattle. I had noticed that my throttle response was a little off, along with gear changes. With the new valve in (at 60k miles) the car drives well again, and I'm thinking the fuel mileage is a bit better also. Don't second guess this bit of maintenance,,this regulates the vacuum system on these engines.

Thanks a lot!
 

I have 147,000 km (90,000 mi.) on my RDX and my shop said "don't worry about it , we'll change it at 200,000 K." My idle has been lower for over a year and my mileage is getting worse, so I hope this PCV replacement helps out both concerns.Thanks!

Vacuum leaks will wreck havoc on fuel mileage, one other thing that was happening when I changed mine out. There was a bit of oil missing between oil changes. The engine was consuming a very small bit of oil before the new PVC vale was installed. Afterwards , been going 7500 before oil change and the
oil is always on it mark.
