Engine Containment – Full Requirement

Engine diaper or catch pan device to capture oil and debris in event of engine failure is mandatory. Where the exhaust header passes directly under the oil pan, a 2 piece diaper may be utilized. Vehicles using OEM manual transmission cases must also have such a device for the transmission, to capture oil and debris in event of transmission failure. If a catch pan device is used, the catch pan must employ a minimum of 2 inch high lips on all sides. Lips must be coved or curved inward, so as to contain oil in the pan. Catch pan must cover the entire area below the engine/transmission. In all cases, lips must be adequate enough to contain oil in the catch pan. Should a competitor spill excessive oil from the catch pan and debris onto the track, he or she may be disqualified from further competition at the sole and absolute discretion of the event director until catch pan is upgraded, regardless of height of pan lips or pan design.
