When the problem of the leaky cam plate reared its head we went right to Raceseng who developed this much improved part. The stock piece is stamped steel that sits on a seam of two aluminum pieces. The RTV job from the factory is prone to failure, and creates smoke as the oil leaks onto the exhaust. The Raceseng Cam Plate replaces the stock steel piece with billet aluminum with an o-ring groove. This greatly improves the seal and less prone to leakage.
