Spark plugs inspection + pcv valve

Is that for the evap canister purge valve? It releases gasoline vapors absorbed from the gas tank.

It's bringing in fuel vapor, as opposed to just venting it, pollution control I believe. The yellow highlighted hose?



Going from memory, the other end of that hose is into the spigot on under side of (yellow highlighted) switching valve?

 

Fyi..I have 152k miles on my prius

04priusnow: How is your OCC mounted? I have a similar OCC & am having trouble finding an acceptable solution. By the drivers headlight is one option. Another is at the drivers side end of the plastic valve "cover". Both places have some room. Creating a somewhat solid mount is the problem for me.

 

@StarCaller mounted his at the passenger side wheel well. There is a threaded weld-nut there (the usual M6), and a close by, similar sized unthreaded hole. That would work if you could fashion a bracket with one bolt and a locator pin, just to prevent it rotating. If that bracket cantilevers back a bit you can just squeeze an OCC in. It is quite close to the engine though, might even get tapped when the engine shifts in it's rubber mounts.

 

I placed it in the space behind driver side headlight.. you can kinda see in the photo.. i just place a rag around it and set it in there.. not much room for it to move around and rag keeps it from vibrating on the metal

Yes, you'll get more condensation (water) in your oil. This will affect engine life.

When I first installed my OCC I neglected to close it's drain valve, though there was a pretty secure rubber cap on the end of the drain, but not really tight. I did a test drive around the block, and noticed an odd sound under light acceleration. Light bulb went on, I checked and closed the drain valve, sound went away.

 

it won't really vent, the positive pressure in the crankcase is too low; you really need vacuum from the intake to suck/
check it for yourself: put a clean, transparent hose on the pcv valve & just let it hang down.
drive a few weeks & check the hose: it will be still as clean as new..../

 

Look for a cream coated oil filler cap. If you get this you have water in your oil. That leads to reduced oil life and bearing life.

PriusChat has had owners reporting oil puddles under the throttle body for as long as there have been Prii, and yet they don't all run like crap. What's making you sure it's the cause of poor running in your case?

While there, have you also cleaned the MAP sensor? That can also get soaked in oil.

 

I tried it for more than 2000 miles; nada, the hose was bone try/
now I'm back to the regular occ setup/
