The fuel injected by the valve is in the shape of a cone. After injection, the valve closes hermetically. Leaky valves cause poor starting of a hot engine.
Defective valves cause the engine to run spontaneously after the ignition is turned off, which will lead to its failure.
Removing
4 cylinder engine
1. Remove the air filter together with the filter element (see fig. Air filter).
2. Remove intake duct.
3. Disconnect injection valve plugs from ignition distributor.
5 cylinder engine
1. Remove the crankcase breather hose.
2. Remove the fuel supply and return lines from the fuel distributor.
3. Disconnect the vacuum hose from the fuel pressure regulator.
4. Unscrew the 5 mm hexagon socket screws of the fuel distributor. Pull out the fuel distributor with valves to the right, in the direction of travel. unscrew the screw (1) and remove the top part of the fuel distributor (2) from the fuel distributor (3).
7. Clamp the threaded part of the hexagon socket head screw 6 mm in a vise and press out the injection valve.
Installation
Attention! Replace damaged O-rings or gaskets, as well as injection valve rings.
1. Install gasket (indicated by arrows) on top of the fuel distributor.
2. Insert the injection valves with new rings into the top of the fuel distributor. Before installing, lubricate the rings with a thin film of clean engine oil.
3. Insert the upper part together with the injection valves into the fuel distributor.
4. Tighten screw (1) torque 10 Nm - see fig. in paragraph 4.
5. Install the fuel distributor on the intake manifold and tighten the fastening screws to 10 Nm.
6. Connect the vacuum hose to the fuel pressure regulator.
7. Put on the fuel supply and return pipes. In this case, connect the black fuel supply line to the fuel distributor, and the blue fuel return line to the fuel distributor and pressure regulator.
8. Connect injection valve plug.
9. 5-cylinder engine: Install crankcase breather hose and secure to oil filler neck. Make sure that there is sufficient clearance to the throttle valve connection.
10. Install the inlet air duct so that the marking arrows on the air duct and the branch pipe coincide (see fig. Air filter).
11. 5-cylinder engine: install the air filter together with the filter element (see fig. Air filter).
