I have a 2005 F-250 Powerstroke diesel 6.0, it has approx 83,000 miles and has developed a whistling noise in the last month or so. It is the whine of the turbo but something different. I have had people tell me it the wastegate off the turbo, but I am not sure.

Please help.

Thanks,

Daryl

 

Might want to go to www.powerstroke.org cause we don't chat too much about diesels here.

It's your EGR cooler and it's one PIA of a job.
