DIY 2002-2009 Gen 5, Gen 5.5, Gen 6 2AZFE Camry PCV Valve replacement with PICS!

[hardtopte72]

I know this is an easy one but just in case I made a DIY for PCV valve replacement.

This DIY will apply identically to all 2AZFE Solara, Rav4, Corolla, Matrix, Highlander, xB1, tC1, etc.

I used the OEM PCV valve since its cheap enough and its a known to work part. I paid 3.85 plus shipping from Greg a.k.a Toyotpartsman. For the 2AZFE there are two part numbers based on years. I would bet all can use the newer one but just to be on the safe side I will list them below.

I did the PCV on both my Camry and Corolla. The valves were identical bodies, thread, and shape. The only difference I noticed was a number 5 stamped on the Camry internal valve and nothing stamped on the Corolla internal valve. Also my Corolla PCV valve had noticeably more rattle than my Camry but the Camry PCV valve was not stuck.

Disclaimer: Disclaimer: Myself or Toyotanation are not responsible for any damage or injury that may result from use of the DIY. Automotive maintenance and repair should be performed by qualified technicians. This DIY is for informational purposes only. Use it at your own risk.

Tools and Parts needed:

3/8 drive 10mm socket
3/8 drive ratchet
3/8 drive extension (at least 3 inch)
22mm or 7/8 Wrench or 22mm deep or 7/8 deep socket 1/2 or 3/8 drive
1/2 drive ratchet (if using 1/2 drive 22mm or 7/8 socket)
New PCV Valve: Toyota or aftermarket if you wish

Part numbers:
12204-28020 - Gen 5 and Gen 5.5 2AZFE
12204-28030 - Gen 6 2AZFE




Step 1. Park car on a level surface and set the parking brake. Shut engine off and pop the hood.


Step 2. Remove the engine cover. Remove the engine cover by removing the 2 nuts from the engine cover with your 10mm socket and ratchet.


Step 3. Locate the PCV Valve. It is located toward the rear passenger side of the valve cover.


Step 4. Remove the PCV valve hose by pulling it straight off. It should come right off, but if it doesn't press the clamp and lower it on the hose and use hose pliers to twist off the hose.


Step 5. Using your ratchet and deep socket or wrench loosen the PCV valve and remove it from the valve cover. Using a wrench is time consuming here. This PCV Valve has 99K.


Step 6. Install your new PCV valve. I am not sure if non Toyota valves come with loctite on the threads or if they are metal or plastic. I would stick with Toyota here. Make sure your PCV valve is snug and tight. No need to overtighten here.


Step 7. Reinstall the PCV valve hose on the new PCV valve


Step 8. Reinstall the engine cover using the 2 10mm nuts.


Step 9. Start the car and verify no surging, hissing, or other weird noises exist.

Step 10. You are done. Admire your work and the 20-50 bucks you save by doing this yourself versus taking it somewhere.

my 2azfe has 145 k miles, how do i know it is time for me to change the pcv?

I'd like to point out that unlike Hardtop's L4, on my 05 L4 engine there are two bolts that slip into two hollow tubes in the black engine cover that are UN-NUTTED
...the photo shows arrows pointing to the crowned top of the tubes



...note that my engine cover is different from that in the series of photos by Hardtop...

I removed my PCV valve and cleaned and reinstalled it...



As I reinstalled the cleaned PCV valve I heard the bolts scraping against the tubes but thought nothing of it as the two nutted bolts held the cover to the engine VERY snugly....

...but later as I drove around town I began to be aware of a rattletaptap coming from the engine and I had this eureka moment that the TONE of the rattle was the same as the tone made by the bolts scraping against the sides of the tubes on the underside of the cover...

...and I figured out that the two bolts were rattling against the inside of the tubes and against the top of the two crowns seen in the photo...

I put some electrical tape around and over the top of the un-nutted bolts and the rattletaptap is no more...


Enjoy your Toy

I think time and mileage would be a good determining force here.

I would say 7 years/90k is a good interval for a $3.85 part.

I've been meaning to tackle this myself, just haven't had the time to do it. Thanks for the writeup.

No problem. I have another one coming this morning too. I made 4 DIY's including the Corolla and Camry.

i would highly recommend the oem pcv valve because i used 2 aftermarket ones and got a buzzing noise..... i wasnt sure if it was a coil or injector or something worse, but i never thought it could be the pcv.....

i ended up letting the dealer diagnose it and it was the pcv and they wanted $36...... as i was waiting i called the parts department at the same dealer and they sell them for $6 which was actually cheaper than the aftermarket one i bought at pepboys ($30 to pretty much turn a wrench...... gotta love the dealer)

anyways with the new pcv on there the car continues to run great

Finally got around to doing it. The valve looked similar to Hardtops when I took it out. Had a little gas on the end as well, though might of been because I just drove the car. Otherwise, a relatively quick thing to do. 5-10 minutes tops.

Good to hear.

Did you use an OEM PCV valve.

Yeah, just picked it up from the local dealer for $6.

Is the process similar on a 2.5l?

Most likely. I don't see a reason to change it pre-100k miles though.

2ARFE PCV valve is not the same design. The PCV valve is located on a ventilation block bolted onto the back of the engine versus the valve cover. The PCV valve is replaceable though, but not as easily accessible.

Part # is 12204-36020

Speaking as a guy who hasn't changed his yet, this was very helpful! At 114K, I'm about to change my Iridiums, I'll change that too while I'm at it. Your article takes away the mystery, I wasn't even sure where it was at this point.
