2001 Dodge Intrepid-105000 miles. While driving I hit the gas pedal hard to pass a car. The car jumped into passing gear suddenly it lunged forward as it would if I turned off the ignition. It then started to make a loud clicking sound. I stopped the car and looked under the hood. I placed a stethascope on both valve covers to listen for noise. I couldn't pin point the sound. It did not sound like a rod or main bearing. There was a lot of coolent coming from the beep hole suggesting the water pump was shot.
I removed both valve covers thinking I would find a broken or stuck lifter. I did not. Next I removed the timing cover to examine the water pump. I removed the timing chain and using a drill, I connected it to the water pump. Spinning it at 2,000 rpm's produced no noies.
I am thinking it might have spun a rod or main bearing. Before I remove the pan I thought I would check with anyone that might have experienced a similar broblem. The reason I am hesitent on pulling the pan is. The sound does not sound like a blown rod bearing. Could it be an oil pump? Any other ideas?
