166 ringing sound from under Timing belt cover
has anybody experienced with such a problem?
166 2,4 JTD suddenly appeared loud ringing sound from under timing belt cover. I thought it was valve or camshaft but sound goes from timing belt cover area and engine performance is good - no overheating, normal consumptio, there are no fumes, no smoke, no lack of power or whatever else, just this f--king noise.
frequency of this sound much lover than crankshaft's revs... when engine is idling it is even possible to count the strokes
could it be tensioning rollers or something else?
Anyway... be free to voice your ideas.
