The Positive Crankcase Ventilation valve, better known as the PCV valve, is associated with the crankcase ventilation system. After the internal combustion process<\/a> in the engine occurs, there are exhaust gases created which get redirected into the exhaust system by an exhaust valve.<\/p>\n

While in the exhaust system, the catalytic converter converts these toxic exhaust gases into less toxic gases. The gases are then released out of the tailpipe and into the outside air.<\/p>\n

However, the catalytic converter<\/a> is not able to convert all of the exhaust gases that are produced from combustion. There are always going to be a small percentage of toxic fumes which seep out of the internal combustion chamber because of a minor pressure leak.<\/p>\n

These gases will flow toward the engine block (aka the crankcase) and end up in the middle of the cylinder wall and piston rings. If these gases were to remain in your engine block, it would create too much pressure there and ultimate cause your engine to get damaged.<\/p>\n
