Ok, I was at the shop today adjusting my valves. I noticed when I would turn the engine by hand (setting tdc) I herd a sound like something metal falling against something else metal. Kinda like a ka-Ching. So after I was done with the valves, I turned the engine over buy hand a few more times and herd the sound at least once every 360 degrees. I have never herd this before and I started the car and turned it off and I herd the sound again as the engine was shutting off. I don't have any drive ability issues or anything like that. I'm just nervous the sound could be something bad wrong that is internal and I may be headed to engine failure. If anyone has any ideas what this could be going ka-Ching inside my engine please tell.
This is my DD and my only car. So I would appreciate any help on the matter.
thanks
Mick
