Illustration 1. The blowby/air flow indicator group in its compact carrying case.The volume of exhaust gases, or blowby, coming out the engine breather(s) can be very helpful in planning engine repairs. Blowby volume guidelines for Cat engines are listed in the Special Instruction that comes with the instrument. The volume of blowby gases can be shown in either liters/min or cubic feet per hr. Air velocity through the radiator core helps to quickly find areas that are plugged or partially restricted. The flow velocity can be shown in either meters/min or ft/min. Illustration 2 shows the indicators on the face of the instrument. A digital value appears when the instrument is used.
