My car has been garaged since early november. Today I went to start the car, I noticed that the engine "clicks" repeatedly and won't go away. As I revved the engine, the clicks clicked faster. The clicks seems to be emanating from the driver side of the engine. I usually start the car every 2-3 weeks and this is the first time it clicked. Any clues what might be the source for these clicks, and what might be the solution to this problem?
