How much can would a catch can catch if a catch can could catch can? ;)

I'm hoping my odds of winning are better than my odds of getting a creative writing award!!!

No problem! Modern engines (and especially this 2.0T) are very complex. Basically, a catch can makes sure that the only thing your engine is burning is air and fuel.

All engines produce what is known as blow-by. As you read, blow-by is a combination of air, fuel, oil and water that pushes past the piston and into the engine crankcase during the combustion cycle. If that blow-by builds up in the crankcase, it can create too much pressure and damage oil seals. To prevent that from happening, the blow-by is vented from the crankcase by the "closed crankcase ventilation" (CCV) system. Due to environmental concerns, the blow-by cannot be released into the atmosphere, so manufacturers plumb the CCV system back into the engine's intake so that all of that oil, fuel, and water can be re-burned and cleaned by the exhaust. The problem with this is that the oil and fuel in the blow-by builds up on intake components, sensors and, in direct-injected engines like the JL 2.0T, the intake valves. This causes issues with airflow and the vehicle computer's ability to control fueling, thus leading to poor running. Eventually, the blow-by builds up on the intake valves so badly that air cannot flow into the cylinder and the valves cannot close completely. When that happens the cylinder loses compression and cannot generate power.

To prevent those issues, a catch can is plumbed into the CCV system to intercept the blow-by before it enters the intake. The oil, fuel, and water are trapped by the catch can and only clean air is reintroduced to the intake. Once the catch can is full, it can be emptied into an oil container and the contents recycled just like doing an oil change.

Hopefully that clarifies thing, but feel free to let me know if you have any questions!

Thanks!
-Steve
