Engine or Exhaust noise?
I have a 2006 Dutch Star with 48000 miles on a Cummins 400 ISL . For the last 7 years this motor has taken me high and low without a problem.
We just drove from Yosemite to Rocky Mountain National park for a first time to look at this park. About a day or so ago I noticed a louder engine noise as I drove out of a Rv park in Utah. I don't know much about deisel engines but the noise reminded me of an exhaust leak or exhaust gasket leak in a gas engine car. It is only noticeable when I accelerate, and not much at idle.
I looked at the flex exhaust tube and did not see a tear, as I have replaced that in the past. The performance is about the same and there are no warning lights or change in temperature.
Can anyone recommend a good, honest, and reasonably priced place in Colorado to have it looked at?
