Vinegar's acidity is what makes it such a good cleaner. Because vinegar is so acidic, it can counteract some icky buildups. It can dissolve away soap scum, brines left by hard water, and glue left behind by stickers.
The PCV valve is a control device which sends partially burned gases that come from the engine's crankcase to the combustion chamber. Its name, PCV means Positive Crankcase Ventilation and is one of the oldest and most used emission control devices.he PCV valve is a control device which sends partially burned gases that come from the engine's crankcase to the combustion chamber.

My Jeeps. The PCV valve is intact, it is the tube that connects it to the air filter housing that is broke. It broke the nipple of the air filter housing. I have two valves, one on the front of the valve cover (near the oil filler cap) and another that is at the back of the valve cover (near the firewall).
