Here’s how I changed my PCV valve hose, and my PCV valve. And, remember, I am not your Subaru Technician – always discuss any suggestions, videos, tips, etc (mine or others) with YOUR authorized Subaru service technician. Follow what I did at your own risk.
ALWAYS double check part numbers for the most recent part numbers. These part numbers are accurate as of 8/2/2023
For those doing it themselves, you will need:
- HOSE ASSEMBLY-PCV 11815AC88D
The new clamps are included with the new PCV hose assembly.
You will also need these for the intercooler.
- GASKET-INTER COOLER 21896AA130
- GASKET-AIR INT DUCT 14497AA080
AND YOU WILL OF COURSE NEED THE PCV VALVE:
- 11810AA210 – PCV Valve and both o-rings
