    One more thread, I hope this would be the last one in the problems section :D
    Anyway, one day I was driving and everything was ok, but the other day, engine started "clicking" in acceleration. When it`s on idle it runs normally, driving in constant speed is normal, but while I`m pressing gas pedal in order to speed up, I hear that "clicking" sound.
    Valves are set, distributor is brand new Ducellier, timing is set (but sound can be heard either on advanced or retarded timing), sparks and cables are new. I really don`t know where and how to look, because it can be heard only while accelerating, not even on higher rpm in neutral.
    You may hear in video what I`m talking about, but the sound on video is not showing the quite actual sound which can be heard in car.



    If anybody has any ideas, feel free to write. Thank you very much.

    Does it click if you remain parked & try to pull away - loading up only the engine? Just possible drive train clicking, not engine clicking.

    Hi Adam! No, I hear it only when speeding up in 2nd 3rd and 4th gear but in 3rd and 4th sound is more likely to hear when the torque is lower. It happens always every time I press the throttle pedal. I suspected on distribution chain but I can`t be sure.

    Hi Mario, check for free play in the timing chain by trying to rotate the camshaft pulley (or the alternator pulley) by hand, firmly - if there is movement in the camshaft but no movement in the crankshaft (flywheel), then there is slack in the timing chain. I had this slackness and found that the tensioner has seized - lack of oil changes.
