Abstract: A bypass valve which may direct excess oil back into the cam chest where the return side of the oil pump may send the oil back into the oil tank. The bypass valve may fit within the bypass port of the cam plate and connect with a high pressure feed. The bypass valve may include a sleeve with a front opening and a needle valve within the bypass valve. The needle valve may be biased in a closed position, sealing off the front opening. When the high pressure feed exceeds a certain oil pressure, the needle valve may unblock the front opening.
