BDE Billet Half-Moon Cam Plugs VG30DE(TT)/RB25DE(T)

Billet aluminum half-moon plugs replace the stock rubber plugs used in the cylinder heads under the VG30DE(TT) exhaust valve covers and both RB25DE(T) intake and exhaust valve covers. Aluminum will not shrink with exposure to heat and oil, and eliminates valve cover oil leaks in this area.

Note: the pockets machined in the cylinder heads have extremely sharp edges that can be dented or have raised burrs which will make installation difficult. Before applying any RTV silicone, test-fit the half-moons dry to check that they sit flush with the valve cover gasket surface. Remove any burrs or sharp edges from the cylinder head pockets using 180 grit wet-dry sand paper with grease smeared on it to catch the filings.

For final installation, apply a very small amount of RTV silicone to the area that touches the cylinder head pocket. Do not use the valve covers to press the half-moons into position - instead, use a block of wood with a small hammer to tap them into position.
