Fuel Injector Leakage

Remove fuel injectors. Mark sequence of injector valves relative to cylinders on each injector valve. Clip injector valves into Holding Fixture (13 6 205). Connect special tool to injector valves. Connect Harness (13 6 206) to a 12-volt battery. This removes the remaining fuel from the injector valves. Lay a clean cloth under injector valves to catch remaining fuel. Connect holding fixture to compressed air connection at maximum 43 psi (3 bar). Residual fuel is now blown out of the injector valves.
CAUTION: Carry out leak test only after remaining fuel has been blown out of injector valves.
Separate harness from injector valves. Install injector valves with holding fixture in a container with hot water at 140-176°F (60-80°C). Regulate air pressure at connection No. 1 on holding fixture to 44 psi. Note volume of air emerging. Permitted volume of air emerging is 2 air bubbles per injector valve within a 15-second period. Injector valves with larger amounts of air emerging must be cleaned. Remove injector valves from water and dry with compressed air.
