Great advice guys, and thanks for the palm read OldTee. The engine was rebuilt about 5,000 miles ago by a previous guy and Im hoping it was a spare clip that fell during the rebuild because I really don't want to rebuild a cylinder. Prschmn, I followed up on your theory and compared the clip with the ones on the top of the spring tensioners I took out. It appears that the previous guy had rebuilt spring tensioners installed from the looks of the bright metal on them. The clips are on both tensioners, so I hope its a clip off of one of the old tensioners. Im not convinced though that this is a tensioner clip because it appears smaller that the ones from the tensioners that I took off (see pic where the loose clip is setting on the tensioner for comparison).
I need to research the wrist pin clip a little more, maybe get my hands on one and compare side by side and hopefully conclude that it is off of an old tensioner. By the way, the engine is out of the car, so this is the time to figure it out.....
You guys are extremely helpful, thanks a million!
