I have the 96 tour.....2.0?....anyway, when I start it I hear what sounds like marbles in a can coming from the engine.

It seems to be from the passenger side. Water pump maybe? Its been like that since I bought it almost 3 years ago and it only had 10,000 on it then. It hasnt gotten worse but is still anoying. Any ideas?

Also, does anyone know of any links that I can check out regarding the instalation of an after market tach?
Thanx
