Hey guys, I'm experiencing some strange noises with my Ahu engine with 220.000 km on it. The first noise is a sort of creaking, it occurs when the engine is cold and it shakes, for example when i shut it off, when i start from a nearly complete stop in second gear without accelerating, when it's a bit low in rpm and i'm turning in a roundabout. Maybe it's the famous harmonic balancer, but there is no noise when the engine is idling, only when it shakes; when it reaches operating temp i can't hear any noise. The second strange noise occurs with the engine in temperature, usually after a long trip (highway driving for example). It's a sort of chirping, with a high pitch, like some metal touching something else. It occurs when i mantain a constant speed (for example 70-80 or 120 km/h). It goes away if i accelerate or if i brake slightly. I'm facing these issues from two years, but one year ago they were less noticeable. It's significant that the noises appear usually in september/october, when temperatures start to decrease, in summer i didn't notice anything. I will try to make a video in the next days. Any suggestion? Thanks in advance.
