VTT 911/930/964T Billet Anodized Single Plug Valve Covers

VTT Billet Aluminum Valve Covers – Porsche 911 (2.0L–3.3L & 964 Turbo Single Plug)

End Oil Leaks. Enhance Performance. Upgrade Your Porsche.

Nobody likes oil leaks — but if you own an older Porsche 911, you’ve probably learned to live with them. Traditional paper or graphite gaskets combined with thin magnesium or aluminum factory valve covers have made seepage almost inevitable.

Those days are over. VTT is proud to introduce our Billet CNC Valve Covers for classic Porsche 911 engines, engineered to eliminate leaks once and for all while transforming the look of your engine bay.

These covers replace the factory leak-prone units with precision-machined billet aluminum pieces featuring custom-molded O-ring gaskets for a perfect seal every time. The result is a durable, reusable solution that stops oil leaks and adds modern performance to your classic Porsche.
