2006 ML with 140k miles. I’d like to change my Pcv valve and hoses. I already have the Pcv Valve (12204-50030) and ventilation hose (12261-50050). Should I also do the ventilation valve cover (12236-50010) and ventilation hose no. 2 (12262-50060)? I’m pretty sure nothings ever been replaced

I would replace all hoses since they are probably 18 years old now.

I have all of these sitting around. All said and done, you're into it for like $130 with all of the hoses. Partsouq had all of them. Be advised that some models have a green check valve while some don't. My 06 does not which required a different hose.


This is most of them. I got these last year and still haven't installed them. Will do it when I do the timing belt and valve cover gaskets in the near future.

Wow! Does anyone happen to have all the hose part numbers? I replaced the radiator hoses when I put a new radiator and thermostat in a few months ago.

@Romanova are all those hoses near the pcv valve or everywhere in the engine bay?

That looks like a mix of hoses for the PCV and the coolant hoses around the throttle body. My PCV hose was super hard and falling apart, so I just ended up using 3/8 fuel injection hose that I had on hand and have had no issues with.
