the circuit. Because of this, this compressing the tappet slightly and producing valve play which is
responsible for the ticking sound. On account of this, the tappet compresses slightly giving rise to a
valve clearance, thus generating a slight ticking sound, which however disappears rapidly ( MAX 10
seconds) once normal operating conditions have been restored.
Anyway the duration of ticking Anyway the duration of ticking sound must be
MAX
30 seconds. If not, the
problem is surely due to the poor quality of the oil, wear or impurities that, transported by the oil, can infiltrate
between the ball valve and its seat inside the piston, compromising the operation of the tappet itself; In these
cases, the only solution is to replace the oil or hydraulic tappets.
The prolonged persistence of the ticking sound or abnormal noise must be investigating in order to prevent
any malfunctions; if necessary, replace the hydraulic tappets and engine oil.
