Thanks for the suggestion. I took a look at it, and it appears to be original. I'll pull it out and inspect it just to make sure.
When I got home, I took off the valve cover and did a closer inspection of the camshaft. The Intake side of the #3 cylinder has some chunks out of the lobe. Could this cause the ticking? I can try to find a new cam, but if this is the problem, what are the dangers of running the engine with this scarred cam?
Any help is always greatly appreciated. Thanks!!!
