Here are some Hints and Tips on how to plumb and connect our breather tanks for maximum performance and efficiency. Remote breather tanks eliminate any possibility of oil residue on your valve covers or exhaust while capturing and isolating residual liquid vapor from escape with hi volume engines. PCV configurations are best to prolong oil life, reduce contamination and promote engine sealing when there is vacuum and the open breather system is a last resort or when running wide open throttle for most of the engine's operating cycle.

Then the contaminants in the crank case are pulled through the PCV breather and into the intake vacuum which is burned in the engine.
