Hi recently noticed (Last few months) a strange chirping/ticking noise coming from the engine bay, did some research and have tried the most common answers, I have ran engine with aux belt removed noise still present, tried applying a small abound of bees wax to the cambelt via upper inspection pannel, no jay there either. Noise seems to go away under load at idle, but present at low revs when driving around town. Cambelt, water pump ect done last year around this time must have only done 1000 miles since any ideas ???
