maybe a little more info would be helpfull, does the sound come from top or botom, front or back? At this point it would be just a wild gues, could be anything from an exhaust leak, to loose plug, to no oil in your powersteering pump or the AOS breahter tube from your cylinder head came off or broke,

Hi everyone, I also have a noise coming from the engine bay. It sounds like a grinding, kind of like when an engine is running with low or no oil. I do have the correct oil level and I change the oil as required. The car runs fine with plenty of power. 1 thing I want to mention, a while back I replaced the AOS and there is a plastic round canister with a really small hose that I broke the little tip on the canister that connect to the hose. I fixed it by connecting the hose to the canister with a wd40 can straw, by connecting the hose to the straw and glued the straw to the canister. It fitted perfectly, but I dont know if there is an obstruction somewhere there or if that canister supply oil somewhere and if that is the reason of my noise. Please help

That sounds like a loose plug to me
