Well on my way to work this morning I heard a funny noise, a load whine followed by a tearing noise. When I got home I discovered my belt to the A/C compressor was gone, and now a piston is busted as the #4 spark plug wire is portruding from the valve cover . Funny thing is the car drove home fine in gridlock traffic. I can't wait to see what the repair bill will be . Anyone have any ideas?
