Hello all, I bought my first car about 6 weeks ago, a mini one from 2007 with 95 hp and about 156,000 km. Unfortunately, the engine makes funny nailing or clacking noises in the idle run. When you drive the engine sounds normal. (Maybe only the noise will be overwhelmed…) After searching in the forum I hit on V-belts and chain tensioners. On Wednesday I changed the V-belt with an acquaintance. This was also necessary, because the old one was very brittle and missed at a point about 0.5 cm of 2 ribs. Unfortunately, this did not help with the noises. As a result, we changed the control chain tensioner yesterday. The engine sounds only minimally better. I would rule out the steering chain that I did not feel a ratchet. Could the wash be caused by broken Hydropulses? I don’t know any more and hope that the experts from the Communtiy can help me. Additional information: If the engine is cold he has sometimes lost some oil. Otherwise the oil has not returned a bit of speed.
