Using an Air Pump (Electric or Mechanical) to Ventilate the Crankcase on 1991-1999 Engines
Effect on the following characteristics:
- De-clutters the engine bay – No
- Simplifies crank case ventilation system – No
- Helps remove more oil from the air – Yes
- Help evacuate the crank case – Yes
- Maintains or improves the stock flow capacity – Yes
- Helps promote ring seal and prevent blow-by – Yes
- Helps prevent oil smoke in exhaust – Yes
- Helps prevent dip stick from popping out – Yes
- Helps prevent oil leaks due to pressure – Yes
- Helps keep intake track clean including throttle body – Yes
- Helps keep intake manifold/plenum clean – Yes
- Maintains or reduces amount of pollutants – Yes
- Maintains prevention of un-metered air from entering the intake – Yes
Consensus: GREAT IDEA!

- Helps keep intake track clean including throttle body – Yes
- Helps keep intake manifold/plenum clean – Yes
- Maintains or reduces amount of pollutants – Yes
- Maintains prevention of un-metered air from entering the intake – Yes
Consensus: BEST IDEA!!!
The Dog II race car has a SR20VE so it uses the late model version of the SR crankcase venting system (explained on page 3). A large hand fabricated air oil separator, with more baffles for better separation of oil, was added. The can drains back into the crankcase so oil will be returned to the crankcase. This works really well. For any engine, especially ones that are raced, the self draining catch can is one of the best bets.
