Thank you for your purchase of Carbon Components Honda v-tec carbon fiber valve cover. As with any high performance part, care must be taken during installation for the valve cover to seal correctly. Included in the kit are 8 washers, approximately .090” thick. These MUST be installed under the valve cover mount studs. This correctly sets the crush on the seals, as these studs need to be raised .090”. Simply remove the 4 valve cover mounting studs at the corners of the head, and place the washers under the base of the stud and re-install. Then remover the 4 cam journal bolts that hold the center of the valve cover, place washers under the bolt head, and re-install. Note that these bolts will have to be tightened with a torque wrench according to the engine specifications.

This valve cover uses the stock seals for the spark plug openings and perimeter. The perimeter seal will have to be modified slightly to correctly fit the valve cover seal groove. In 8 places, at the corners of the cam shaft semi-circular openings, the stock seal has extra material on both sides. This will have to be trimmed off with a razor blade. This has to be done anywhere the side of the seal is too large for the groove. Once the seal is uniform in thickness you are ready to install. Place the valve cover upside down on a towel to protect the top surface. The seal fits tight, and must be lubed with grease, then press firmly into the groove. The cam openings are NOT the same diameter at both ends, and care must be taken that the seal is installed correctly. Make certain there is no interference between the valve cover and the cylinder head, this might require a little sanding/filing on the valve cover around the cam journal openings.

Carbon Components carbon fiber valve covers have a true race car heritage, and they must be installed with the same attention to detail any race car would require. You will find the Honda v-tec valve cover is the lightest, most intricate product of it’s kind, and we hope that this is an outstanding addition to your car.
