Oil Catch Can
I installed a BT oil catch can on my SRT to keep the engine clean.
I have heard two other things about the catch can, and I wonder if they are true: 1. It can slightly increase power. 2. It can make your engine run rich (gasoline smells can be detected at a 65 mph cruise). Anyone else hear this? |

OK, another question: How exactly do these things keep the engine clean? Until recently, I'd never even heard of oil catch cans, and I'm not sure what they're even supposed to do.
There are various negative effects when excess oil vapor contaminates the intake system from the stock PCV system, such as: ·Throttle body and/or MAFS (Mass Air Flow Sensor) malfunction or failure. ·Air filter, intercooler (if equipped) and intake ducting contamination if oil pools and run back out the intake system after engine shutdown. .Reduced octane of the air/fuel mixture, which can cause detonation and the ECM (Engine Control Module) to retard timing, thereby reducing engine power. ·Excessive carbon build-up on valves, piston crowns, combustion chambers and spark plugs. This also increases the chance of detonation and power loss. ·Increased emissions & possible contamination of catalytic converters and oxygen sensors. Dodge does not install them due to the expense, and the fact that they must be emptied every 500 miles. This creates a problem of frequent maintenance, as well as possible contaminants. |
A very thorough explanation. Thank you, Cuda. :)

Another example of oil catch cans. Top Fuel Dragsters and Fuel Funny Cars use oil catch cans "Puke Cans". Funny Car cans are located at the rear of the car, can't miss it when the body is off its about the size of a gallon paint can. After a good pass there is a inch to 3 inches of oil in the can. Drop a hole or two and it will fill.
