header mounted crankcase evacuation

[agawam]

I set one of these systems up on an engine to eliminate the PCV. I used a dodge oil cap several feet of heater hose a diverter valve connected to a pipe and an open breather on the other valve cover for crossflo. the pipe is cut at 45deg angle and welded into the headder collector so the open part is facing rear,this creates a vacume to scavenge the crankcase,the diverter valve(the oneway valve from an AIR system)keeps exhaust from going back to engine.This gives higher manifold vacume if you eliminate the PCV completly.worked good
