The oil plug located at the ends of the rocker arm shafts. for 1 car it took 4 plugs.
When you replace the plugs, check that the rocker shafts are ok, they are not damaged on the sliding surface against the rocker arm, then clean them carefully and replace the plugs at the end of the shafts. Turn the shoulder the right way, check the picture. The oil channels must point in the direction of the arrows, one towards the carburettor and the other oil channel towards the camshaft.
