Positive crankcase ventilation (PCV) system
The PCV system in modern day engines is designed to remove blow-by gases (un-burnt fuel-air mixture that escapes past the piston rings on the compression stroke). These crankcase gases can foul the engine oil or increase the crankcase stress. Additionally it raises the acidity levels in the oil, which breaks down the oils ability to lubricate properly. Filtered air supplied to the crankcase from the intake hose through the valve cover mixes with the blow-by gases and funneled out of the valve cover vacuum in the intake manifold through the PCV valve. The PCV is a tapered plunger and two springs, and limits airflow based on intake manifold vacuum. Most NA cars are not set up with sufficient PCV systems to exhaust these pressurized conditions, the RIPP PCV eliminates the following conditions.
• Blow by
• Crank Case stress
• Sludge build up
• Oil acidity levels

Under idle, deceleration and cruise conditions the blow-by gases are minimal, the engines vacuum will do a sufficient job in removing the pressure built in the crankcase. However, under boosted conditions and heavy acceleration, the PCV system is under a much heavyier load because blow-by gases are at their highest, a completely normal condition. The intake manifold becomes pressurized and the plungers seat on the factory PCV is forced closed preventing air from entering or exiting the crankcase, ultimately building excess crankcase pressure. Additionally, when the manifold is pressurized the excess blow-by gases now under pressure flow out of any part of the engine it can find such as the valve cover seal or gaskets, oil dip stick tubes, valve cover relief vent and various other “escape routes” the pressure manages to find.
RIPP Modifications developed a low cost and simple solution to this problem, a one-way valve that modifies the operation of the PCV system and prevents air from entering the crankcase through the factory PCV valve or the intake hose. Used in conjunction with the Oil Catch Can system we offer you will eliminate the conditions described above. The larger valve assembly installs in the hose that connects the rear rocker cover to the intake hose. Our valves allow air to flow through them in only one direction, the crank will flow only away from the valve covers, maintaining a partial vacuum in the crankcase at all times. The new system will increases engine power and response because power is not wasted compressing air in the crankcase on the downward piston stroke.
This method of releasing crank case pressure is time proven and practiced across the board by all professional tuners and engine builders, no matter what engine you choose to run. However, the RIPP valve is derived specifically for the engine supported in its program, a perfect match for your application. The valve comes with instruction on how to best utilize it in your application, high compression, NOS or Forced Inductions engine will all benefit from it. |
