From the engine!!! Now what do I win!






On a serious note, its always hard to diagnose a noise from a video. You definitely have a lifter tick sound and you also have a slower tick/knock. The slower tick/knock could be a bearing or it could be an exhaust leak. The best way to figure where its coming from is find out if the noise is louder from underneath or on top. Does the sound get louder when you rev it or does it go away? How is the oil pressure? How many miles on the engine? Have you done any recent work?
