Hello friends, first of all, I have a 206 1.6 gasoline Quicksilver vehicle. I did not mind the rattling noise coming from the engine of my car at first, but recently it has increased significantly. I went to a mechanic, he told me there was a problem with the valve lifters. I said to do the valve lifter set, which he said was 500 TL, I said to do it, he could not do it, I went to another mechanic, the cups, gaskets, camshafts were changed again, still the noise did not stop. I went to more than 20 mechanic services so far, they kept asking about the valve lifters, none of them could understand anything. Is there anyone who can help me, please help me.
