It is recommended that to ensure compliance with profile gauges used during technical inspections that engines be cleaned after practice prior to the engine being sealed. This should include the head, piston and restricted exhaust headers (Micro Swift, KA Jr, X30 Jr). Engines run for several races without being cleaned will most likely not comply with the profile gauges. See 401.1.3
