Pan Evacuation System
The B&B Evacuation System is designed to lower the pressure inside the oilpan and crankcase. This allows the use of low tension oil rings for increased performance, improves oil control, and reduces leakage past seals and gaskets. Drag racing pan evacuation systems use both intake manifold vacuum and exhaust pulses in the header collector to evacuate the crankcase; circle track versions are plumbed to the collectors only. Both kits include all necessary oil separators, check valves and fittings.
