The VTT B58 Head Port Check Valve Kit is designed to convert the factory head ports used by the OEM low-side PCV system. These ports in the cylinder head utilize engine vacuum to evacuate crankcase gases, but in the process, can allow oil to enter the intake manifold, leading to valve carbon buildup and other performance issues over time. VTT's Billet Check Valve kit converts the head ports into a robust internal PCV system using precision-engineered check valves. These one-way valves allow vacuum to function as intended while blocking boost pressure from entering the crankcase or charge tract.

The EGR valve regulates how much exhaust gas is recirculated back into the engine’s intake. Rather than allowing all exhaust gases to exit through the tailpipe, it redirects a portion into the cylinders to mix with the incoming air-fuel mixture. By lowering combustion temperatures, this process helps reduce harmful NOx emissions, ensures compliance with emissions standards, and can even contribute to longer engine life in some cases. If your EGR valve fails, replacing it promptly is essential to keep your vehicle running clean and within emissions regulations.

The Pressure Control Ventilation (PCV) valve is designed to route high-pressure blow-by gases from the crankcase into the intake manifold, relieving excess pressure while recycling gases back into the combustion process. When the PCV valve fails, it can lead to excessive oil consumption, rough idle, and stored engine fault codes. Replacing a worn or faulty valve restores proper crankcase ventilation, smooths out idle, clears codes, and helps keep your engine performing at its best.
