I was directed to this site from member at marauder.net today. I've been trying to find s tick in my motor for almost 6 months now. When it started it was in the 20's outside and is a mechanical sounding tick. It only happens when the car is warm. As it warms up it slowly starts to happen and is the loudest around 1500-2000 rpm.the car runs smooth through the rpm range and had good power last time I drove it when this started. So far I have pulled the heads, had them gone through, decked full valve job. They replaced 1 exhaust valve that was burnt and all the exhaust guides. The shop said nothing in the heads looked like it would cause a tick. I put all new lifters in, new oil pump, all new timing components, 97 cobra intake cams, and advanced them 8 degrees with the advice of a member on the other site. I've used a stethoscope and determined the noise is coming from the passenger side head. I replaced the cam followers for the first cylinder (all 4). Checked all the exhaust cam lobes and there all the same. I'm out of ideas with this thing and am about at my wits end. Any info you guys might have is greatly appreciated! The you tube link below is my car do you can hear the noise. I realize its not the same as real life but its the best I can do. Thanks again guys!
