JDC Titanium V1 Oil Cap

The JDC Titanium V1 Oil Cap provides a very tight lock and uses an OEM Mitsubishi gasket for a leak-proof seal. Each cap is professionally CNC machined from a single piece of 6AL-4V Grade 5 Titanium and we've incorporated the bottom locking collar into the design and got rid of the screw/nut that would normally be inside your valve cover! Each cap is laser etched with the JDC logo on the center and is hand polished before receiving our proprietary cold anodizing treatment for colors that will last for years to come!

    The JDC logo will be straight facing the front of the engine bay when tightened all the way. Adding a little oil to the bottom of the seal may also help. This tight lock provides a leak-free seal from day one that will last many years!

    Please note that in some cases, the new seal may not have as much flexibility as one that has gone through heat cycles. This can cause the cap to be difficult to turn all the way. If you experience this issue, we recommend tightening the cap as much as possible without using excessive force. As the seal becomes warm and softer over time, it should allow you to tighten the cap the rest of the way.

    GR5 Titanium (Grade 5 Titanium) is a premium alloy composed primarily of titanium, with small amounts of aluminum (6%) and vanadium (4%) for added strength and versatility. Renowned for its exceptional strength-to-weight ratio, GR5 Titanium offers superior corrosion resistance, excellent heat tolerance, and remarkable durability. This makes it an ideal material for aerospace, automotive, medical, and high-performance applications, where lightweight strength and longevity are critical. Its ability to be anodized into vibrant colors further enhances its appeal for customization in industries like motorsports and jewelry.

    How Do I Keep My Titanium Products Looking Brand New?

    Installing: Wear gloves when installing titanium parts to prevent oils from your hands causing a "faded" look. After installation, clean the part before applying heat to avoid baking oils onto the surface.

    Cleaning: Use our JDC Titanium Cleaner, designed to safely clean titanium without damaging the finish. Alternatively, clean with soapy water, a microfiber towel, or Windex, rubbing alcohol, or Clorox wipes.

    Avoid: Harsh chemicals like water spot remover, engine degreaser, brake cleaner, metal polish, or acidic cleaners—they can damage the oxidized layer and remove the color.

    Tip: Always clean when parts are cool to avoid water spots or tarnished finishes.
