Can you drive without PCV valve hose?
If you need to drive a couple miles to get the parts needed then plug the vacuum side of PCV line and it may be okay to drive a short distance since running longer than this may cause the pressure to build up in the crankcase and cause oil leaks and engine will run lean or rich without a properly functioning PCV system via
What is the breather hose for?
This is where breather hoses come in: plastic or rubber pipes that conduct combustion chamber gasses from the engine to the intake system, thereby allowing the hydrocarbons present in these gasses to be reused. via
Can engine run without PCV?
What Happens If You Run A Car Without A Pcv Valve? Rubber hoses are used to attach PCV valves to intake manifolds. You will not be able to attach the hose to the engine if you remove the PCV valve, and there will be a massive leak of air into the engine.

A stuck closed PCV valve results in excessive crankcase pressure. It forces oil past the engine's seals and gaskets. A stuck open PCV valve or leaking hose results in a large vacuum leak, a rough idle, and drivability issues like surging. via
What does PCV stand for?
“PCV” stands for “positive crankcase ventilation.” It is a one-way valve attached to the crankcase. Your vehicle's crankcase holds your motor oil, and is located at the bottom of your engine. It produces gases when your engine burns fuel. via

There is no specific lifespan for your car's PCV valve. It lasts as long as it lasts. Regular maintenance will help provide a longer use life, while neglecting your regular oil changes will shorten it. Ideally, the PCV valve should be changed with every major scheduled service (30, 60, 90K, etc.). via
Does PCV valve affect performance?
Because the PCV valve controls the airflow between the crankcase and the intake manifold, a broken PCV valve can have the same symptoms as an intake air leak, which can cause the idle RPM to get too high and other strange idle behaviors like very rough idle. via
What happens when engine breather pipe is blocked?
If an engine's breathing system should become blocked or restricted, the crankcase will pressurise causing any one or more of the following problems: The oil/air mix will force its way out through any other convenient exit e.g. oil seals, dip stick, filler cap, etc. via
Does PCV valve affect idle?
a faulty pcv valve can cause a number of problems: 1. rough idle or stalling: if the plunger is stuck open, the pcv valve will allow too much air to enter the engine. this can cause a lean air-fuel mixture, resulting in a rough idle or stalling. via
Does a bad PCV valve affect gas mileage?
Poor fuel economy is possible if the PCV valve hose is clogged or leaks. There are many reasons why the Check Engine Light comes on, and one of them is a failing PCV valve hose. via

Is PCV valve delete pros and cons?
There really are no cons to a functioning PCV system besides picking up a minor amount of oil vapor along with the abundance of crankcase pressure and contaminated vapors the system is used for. A separator eliminates that con if it's a big deal. via
Can I use wd40 to clean PCV valve?
Oftentimes, you're better off simply replacing the valve which is difficult to clean even when removing it. However, there is one option you can try. While the crankcase tube is disconnected, you can attempt to spray WD-40 down into the tube. Leave the tube up to get the penetrator to the valve, thus cleaning it. via

What is the most common problem with PCV valves?
Engine Running Lean/Rich & Poor Fuel Economy
One common bad PCV valve symptoms is poor fuel economy. A malfunctioning PCV valve will throw off the ratio of the air and fuel mixture, which needs to be precise for optimal combustion. via
Is a PCV valve a check valve?
