To perform some repair and adjustment work with the VAZ 2107 engine, the gas distribution mechanism must be set according to the marks. They are applied both on the camshaft gear and on the crankshaft pulley. To perform this work, we will need to perform some preliminary steps, namely, removing the valve cover from the engine.

To do this, unscrew all the fastening nuts that are located around the entire perimeter of the cover with the head with a crank, and remove it, after which you should pay attention to the camshaft gear. It is necessary that the protrusion on the lid coincides exactly with the mark on the star, which is clearly shown in the photo below:

To rotate the camshaft, you can either use a large wrench and turn the ratchet, or with your hands, grasping the crankshaft pulley.

We also immediately pay attention to the crankshaft marks and the central risk of the engine front cover housing - they must also match.

It is with this position of the pulley and timing star that cylinder 1 or 4 is at TDC - top dead center. Now you can proceed to the implementation of those procedures that are planned further, either setting the ignition, or valve clearance adjustment etc.

Questions and answers:

How to correctly align timing marks on a VAZ 2107 injector? The car stands level and motionless (stops under the wheels, gearshift lever in neutral), the cylinder head cover is removed, the crankshaft is turned with a 38 key until the marks on the pulley and on the timing sprocket are aligned.

How to set ignition tags on a VAZ 2107 injector? It is impossible to install the ignition on the injector manually, since the moment the spark is supplied is determined by the crankshaft position sensor, and it is controlled by the ECU.

What should be the ignition timing of the VAZ 2107 injector? If the ignition is set on the carburetor, then the middle mark (92 degrees) is selected for 95-5 gasoline. In the injector, the ignition sets the control unit based on signals from different sensors.
