Today I found what other equinox and terrain owners warn about. A PCV hose frozen with moisture. Supposedly when this hose freezes it can blow out the rear main seal, cause oil consumption, etc. The fix for many is an oil catch can. But wait, this isn’t oil blow by this is water and condensation. Can somebody explain to me what the frozen hose is and what the hose marked in red going into the intake and the sensor next to it in blue does/is. I need some clarity on what is the clean air intake and where the PCV valve and exit of blowby gasses.
