I have been hearing an intermittent noise that sounds like it's coming from the engine area. At first I thought it was air in the power steering pump. However, when I got a shorter belt and ran the engine without the power steering pump, the noise still came back at times. Today, I ran the car and and listened trying to find the source. Whenever the noise appeared, I pushed on the driver side side pipes using some welding gloves. Each time, when I pushed on the side pipe, the noise went away.

Has anyone ever heard of something like this?

I will be playing around with the exhaust to try to fix it, but if anyone has any ideas, I sure could use the help.

Thanks
