The valve timing is adjusted correctly when the piston of the 1st cylinder is slightly below TDC, and the valves of the 4th cylinder overlap (those. one opens, the other closes). In this case, the following should be observed.
The mark on the camshaft wheel should be opposite the mark on the crankshaft gear.
The mark on the timing cover must be opposite the pulley mark.
The runner of the ignition distributor should be opposite the label of the ignition distributor housing.
