VTT B58 TU BILLET CNC Valve Cover

Description

VTT Billet Aluminum Valve Cover – B58 TU

The Only Billet Valve Cover Option for the B58 TU Platform

VTT is proud to introduce our B58 TU Billet Aluminum Valve Cover, designed for enthusiasts looking to enhance both the performance and appearance of their engine bay.

The OEM plastic valve cover is known to crack over time and contains a problematic built-in PCV system. Our billet cover eliminates those issues and gives you complete modularity and control over your PCV setup.

We recommend pairing it with our B58 TU Catch Can Kit for the ultimate crankcase ventilation solution. Additional breather options—including our oil cap breather and one-way stainless breathers—are also available to further enhance your setup.

Important Installation & PCV Notes

Installing an aluminum valve cover removes the OEM-integrated PCV system. If you do not replace it with an external PCV system, your B58 may smoke or bypass oil, especially under boost.

We strongly recommend:

• Adding an external low-side PCV to maintain crankcase vacuum at idle (assists with turbo oil drainage)

• Blocking off head ports to relieve pressure on the valve cover gasket and keep boost out of the crankcase

• Using our Modular Catch Can Kit and Head Port Block-Off Kit for best results
