07 6.0 loud squealing
HELLO EVERYONE.
WELL I DON'T KNOW WERE TO START. I HAVE A 07 6.0 AND I NEED SOME HELP. FIRST THING IS I JUST HAD MY ENGINE BULLET PROOFED AND NEW HEADS PUT ON. I INSTALLED A SCT TUNER. WELL ABOUT A WEEK AGO I WAS ON MY WAY TO WORK AND OUT OF NO WHERE I STARTED GETTING THIS HIGH PITCHED SQUEALING NOISE, IT ONLY DOES IT WHEN I REACH ABOUT 12LBS OF BOOST ON UP. WILL NOT DO IT WHEN IN PARK. I TOOK THE TURBO OUT AND INSPECTED EVERYTHING. I DID NOTICE I HAD A LITTLE PLAY IN THE TURBO. ALL HOSES AND BOOTS WERE FINE. CHECKED THE Y PIPE DID NOT SEE ANY CRACKS. PUT EVERYTHING BACK AND STILL GETTING THE NOISE. I ALSO REPLACED THE CAP FOR THE COOLANT. CAN ANYONE HELP ME

Check the band clamps to see if they are tight enough. I had a similar issue and replaced both band clamps for the down and up pipes on the turbo and it turned out to be the little one on the egr cooler.

Could be the exhaust manifold, an up-pipe leaking or the flexible coupling. Take a look at the flex joint for carbon or black looking dust.
Also Ken, take the CAP LOCKS off please... kind of hard on the eyes, like I'm reading a Naval message.
