PLP-94

Bought my 2021 TLX A-Spec in June with 37K miles. Going through the list of items that need to be replaced and started with the PCV Valve.

Time Required:

• 5 - 20 minutes depending on your aptitude

Tools Needed:

• 1, 10mm socket
• 1, 10mm wrench
• 1 PCV Valve (Part # = 17130-RPY-G01)

Steps:

1. Open the hood, look for the large wiring harness on the RIGHT side of the engine bay
2. Use the 10mm socket wrench to take off these 2 10mm bolts and set them aside. Purpose is to loosen the wiring harness to give you more room (picture #1)
3. Next use the 10mm wrench (I have a ratcheting type wrench) and take off the PCV valve bolt. It may make a 'snapping noise' as you break the factory seal on it (picture #2)
4. Remove and replace the PCV value. Apply a light layer of grease on the 2 inner O-rings on the new PCV value. - Part # = 17130-RPY-G01
5. Replace the 3 bolts you took off above. Do not over tighten them because of the plastic surrounding material.

Notes:

• The PCV valve is NOT part of the MM. I like to replace them every 30k miles so the valve cover gasket doesn't start leaking due to high pressures in the valve cover due to a clogged PCV. Old PCV, when shaken, makes no sound. NEW PCV when shaken, makes a clicking sound.
• Picture #4 is one of my favorite tools - an electric socket wrench. It makes taking off small bolts and trim pieces a snap. My last car - Q60 convertible had 20+ 10mm bolts holding on the bottom plastic protective tray.
• NEXT MOD: Replacing the exhaust system with a Type-S exhaust (picking it up this weekend).

Thanks for sharing this. I usually do all of my own maintenance, but after I bought my car CPO I had one free maintenance visit from Acura, so I took it to the dealer with about 32,000 miles on it to perform the B127 maintenance. My SA recommended replacing the PCV but I declined. Glad to know it's easy to do. I may do it myself during my next maintenance job.

What's crazy at the Acura dealer I picked the part up at, they don't even stock these PCV valves. They have to be ordered and they arrive the next day.

More DIY's coming soon. Just replaced my exhaust with a Type S exhaust. Rather simple to do but the new look it gives the car is incredible


ORIGINAL on LEFT, TYPE S on the right.
