Hey guys, I have a 68' Camaro with a 355 small block.. Very cookie cutter engine for a 68'....The engine was rebuilt beautifully by a reputable mechanic in my area around 6 years ago. Since then I have had no problems until now. I pulled it out of cold storage a few months back and despite a dead battery it ran just fine. But because I chose to take it to a different mechanic for an oil change and a quick tune up, I now have a laundry list of problems. Most of which I have fixed myself. But I simply cannot figure out why my engine ticks as soon as i shut it off.. whether I start it up for a few min, or drive it all around town. Has anyone had this problem before. Advice would be appreciated.
