Hi guys, I got a problem on my BMW 92 525i (152,000 Miles) started a weird sound for past few days. Its kinda tik-tik-tik....... Sound which is very clear audible when idling, and goes on faster with RPM. I tried to hear where its coming from but could not find what is causing it, but its coming form some where at top of engine. Additionally, when I start my engine in morning (when engine is cold) then I don’t get this sound until I drive at least 5 miles(until engine get hot). Can any one of you guys suggest me where should I start looking and what are usual suspects in this kind of symptom?

Thanks a lot
