On the Gen 1 B58, the PCV diaphragm built into the valve cover can crack or tear with age. When it does, the engine loses crankcase vacuum and may start smoking. VTT's kit replaces the plastic cap and diaphragm with a billet cap and gives the cylinder head ports a dedicated vacuum path to the intake manifold.
What you get
- Billet PCV cap in place of the factory plastic cap and diaphragm.
- Low-profile billet banjo fitting.
- Vacuum/boost adapter and a hose with a built-in check valve, which keep low-side vacuum under control.
- Catch-can ready. The connection can tie into a compatible low-side catch can.
Good to know
- VTT suggests pairing it with its B58 high-side catch can and crankcase breather for a complete ventilation setup.
