Hi everyone,
Recently bought an used Opel Astra H (1.7 CDTI) (74 kW, 100 HP) it has 164 000 km on the clock.. It's my first diesel and it's a bit noisy but I've heard it's common for 1.7CDTI engines..
The thing few "experts" have told me is not okay and doesn't seem normal to me is that when I drive at low revs (at 1500-2000) and press the throttle suddenly to 1/2 or 3/4, or floor it, revs climb to aprox 2100 and then I hear this strange click sound from the engine, its hard to describe, coming from the middle or the right side of the engine.. couldn't quite locate it.. it's like metal hits an another metal.. immediately after that sound, the turbo kicks in, and a "puff" of smoke appears from the exhaust.. and if I keep accelerating there is no visible smoke, just that initial "puff" (a small cloud of smoke).. color of smoke is dark grey - black or something.. sometimes there is no this sound (then there is no "puff's" and no smoke from the exhaust).. and sometimes there are two of these "clicks" (and still one "puff" of smoke )..
Is this normal or something is wrong? If something is wrong, what could be wrong?
Thanks in advance to evereyone that post here and try to help..
EDIT: Here is the video of the sound.. the sound is heard at 16 sec and at 23 sec..
