6.0 engine whistle and whine
Leaving for a trip this weekend and need to tow my car. I brought it in to my mechanic and he said the sound I was hearing was it was in need of the bullet proof EGR . 2500 bucks later it is still doing the same thing. It only happens going up a large hill under full power with a 9000lb trailer. No difference in temps on any of the gauges. No other real symptoms. Any thoughts ? Thanks.
