Title. Not sure what’s going on here.
Few weeks ago, noticed some positive crank case pressure when I opened the oil cap. A decent bit of pressure was coming out and a low heavy note came out of the engine.
I’ve experienced this before on my older Volvo and have fixed this situation before… Well after a new Pcv valve (the old one was partially clogged, new one was definitely functional) it still does the same thing.
Whats going on here? I made sure to change the hose that goes from the valve to the intake as well just to make sure I wouldn’t have issues and here I am.
