Valve clearance adjustment instructions

Model: Peugeot 206 MK 1 - Years 1998-2012
Part: Valve

When the intake and exhaust valve opening system takes excessive play, a clicking noise is heard coming from under the tappet cover because, due to the excessive play, the cam hits the valve plate: Ã It is therefore possible to record everything by adopting a special thickness gauge. Therefore, once the tappet cover and the timing belt cover have been removed, rotate the crankshaft pulley in order to align the timing references and position the exhaust valve of the first cylinder in the maximum open position: in this configuration, evaluate and, if necessary, adjust the clearance of the intake valve of the third cylinder and that of the exhaust of the fourth (in French engines the numbering of the cylinders starts from the side opposite to the distribution and therefore the cylinders are counted from right to left looking at the engine from the front; the intake ones are the rear ones and the exhaust ones the front ones) Adjustment is done by loosening the lock nut and screwing or unscrewing the adjusting screw as needed; once you are sure of the necessary play, retighten the lock nut. Rotate the crankshaft again to fully open the third cylinder exhaust valve and adjust the fourth cylinder intake and the second exhaust. Then proceed with positioning the exhaust of the fourth cylinder at maximum opening and adjust the intake of the second cylinder and the exhaust of the first. Finally, position the exhaust of the second cylinder at maximum opening and adjust the intake of the first cylinder and the exhaust of the third. The sequence is therefore that of the explosion: 1342. Finally, reassemble the tappet cover.
