I need help this is my first post and issue with my 07 250 6.0 I drove 1000 miles and I noticed a leaking noise . Thought it was a tire but found out it was coming from my engine and now my turbo makes a loud whistle when I push the gas. Has anyone else had this problem? Please help...

Most likely a cracked expansion joint in one of the up-pipes, more commonly the right side. This is commonly referred to as the turbo y-pipe. Notable symptoms are a hissing noise audible outside the truck at idle, heavy exhaust fumes in the cab with the ventilation system on and black soot on the firewall behind the engine. I would start by looking there...

Thank you for your early response. I m going outside now to look at it. Is this something that I can do or is it a job for a shop? Once again thanks for the help!

theres ways to test for leaks too. on the old 7.3s we used to put a schrader valve in a plumbing cap and filler up with air and see where leak was.

No need for any schradar valve, way too much work. Just hook up a shop vac to the tailpipe with some duct tape and turn on, then check around the exhaust up pipe and turbo. You should be able to find the leak in no time. I had a similar leak and found the leak in about 20 seconds. I will second the cracked expansion joint, they are not very good, there are aftermarket ones that are much better.

Not a bad job to repair, but the turbo has come off and a fair amount of time, but do-able.
