The PCV hoses are responsible for routing blow-by gases from the crankcase to the intake manifold. If these hoses become disconnected or damaged, the proper flow of gases is disrupted, leading to the P04DB code. Age, heat, and exposure to oil and other chemicals can cause the hoses to crack, harden, or deteriorate, affecting their performance. 2.
If you disconnect the hose, no suction is present, and fumes build up in engine crankcase, causing rapid deteration of engine oil due to gas that seeps past the pistion rings into the crankcase, and delutes the oil so in about a month, instead of having a 10W 40 oil, you have a 10W 25 oil, so less luberacant for engine, more weare!!!!

That hose is just a complete pain in the ass. I tried pliers, screw drivers, everything. The hose gets so brittle as it ages, it snaps apart very easily.

You can leave the tank on and not bother disconnecting the lower end of that hose on the crankcase. I'd still let the crankcase vent somehow out of the hose and not plug it, to where and how I don't know.
