Hello people, I hope I find help here. I drive an Alto GF and at 30000 kilometers the engine has started to clack in the stand gas, I drove the workshop and they have tested the valve play, exchanged valve compensation nozzles or replaced it, and I would not know how many cups the engine has but 8 pieces have been renewed, I have made the car pick up on the yard and it is gone away driving home and it has been from day to day more and more internal Half a week again as before, called in the workshop and he doesn’t know what to do on it I told him either you put it in order or give me my money back he gave me the money and I’m steamed, it didn’t bring anything. Now I drove so 25 thousand kilometers further and it keeps me annoying. Now the question what can it be? Can you help me? MFG Alexander5
