PCV Valve or bad head gasket?

Mmmm ok, kind of ought :/

Today, I was parked for about 1-2 hour inside the car with the a/c on and the a/c for some reason the output of air was 2 low and the temperature was warm. When I got home and checked under the hood, the oil that was leaking from the ocv valve reached the top of the alternator near the pulley

I have heard other Yaris owners state that the a/c while no moving does not work nearly as well. I have yet to be stopped long enough (nor do I run my a/c enough) to notice this myself, but something to think about depending on how warm the air was coming out and how hot the ambient temp was of the outside air.

As a side note. After 150km of driving since I cleaned off the oil on the outside of the OCV it has yet to build back up. Likely it was just there from when my valve cover became loose. With that said if your's is leaking that much then definitely change it out as soon as you can as it's obviously damaged to be leaking that bad.

Yep, just bought a couple of hours ago the OCV valve, In Puerto Rico temperatures fluctuates between 80-95 not very helpful LOL I'm gonna try and do a DIY of changing the OCV for purposes of Yaris Forum
