An Open system will also be more effective at removing the crank case pressure as a whole.Īn Open system simply caps off the intake port where the air would recirculate into the intake (most MAF sensor vehicles will need a tune update for this to be possible). A vented catch can will 100% eliminate an oily air charge from getting into your intake (Most Important). On a Nitrous or Boosted engine it is even more detrimental.įor a modified and high horsepower application, this is really the only logical choice. Oil being present in a fuel charge can cause detonation and tune issues. However, that cleanliness is not the only drawback. This is why factory intakes usually are oily and sludgey on the inside. Additionally, because the air is brought back into the engine, it will contain a certain amount of particulate. This style system can be a vacuum leak if simply disconnected and not capped off, and can change how your tune acts. These valves insure that air enters in a one way fashion. The air coming out the otherside of the can then enters back into the intake after passing a PCV check valve. With the hopes of it collecting at the bottom of a container, some drain back into the oil pan, some do not. This is nothing more than a can that oily pressurized air passes through in an attempt to knock the oil out of the air. There are two types of catch cans that exist, but only one truly is appropriate for high horsepower applications.įactory vehicles are often equipped with a closed system particulate catch can. Not allowing the excess crank case pressure out can cause even more issues including: seal failure, loss of horsepower, oiling issues, and even fire hazards as oil exits seals. Pressure built by faster moving engine parts, wider ring gaps, looser tolerances, and stresses on components can allow for crank case pressure to increase. High horsepower and more notably BOOSTED engines create conditions in an engine that are not typically or ever seen in their factory form.
