Crankcase Vent Valve, Aftermarket - B58A - F22 F3X G01 G02

The B58A turbocharged engine uses a spring-loaded rubber diaphragm to control crankcase pressure. Over time, this component wears and begins to leak oily vapor past the seal. There are tell-tale signs of oil leaking around this plastic cap and the unpleasant burning oil smell. This kit will allow you to restore proper operation of the PCV system.
