Ford Diesel engine blows off the intake rubber intake hoses, blue in color with 7.0 Liter. If you have a problem with this engine as stated above there is an updated hose for the intake tubes also remove the intake pipe on the turbo side of the turbo remove the 10MM bolt that holds the metal tube on to the block and remove the clamp on the turbo, remove tube. Next look at the turbo shaft inside do you see oil in the turbo? If no then grasp the turbo shaft and try moving it up or down and in and out. Any Movement The turbo needs to be rebuilt before replacing the Turbo hoses. If there is oil in the turbo then it needs to be rebuilt so stop at this time and decide what you want to do with it. The turbo also has a flapper valve inside the turbo that goes bad at about 100,000 this is the boost waste gate and boost flapper valve, it is an internal gate unlike the mechanical ones on most turbo. If you have low power check the boost pressure with your boost gauge if you have less than 12 pounds of boost then it's time to look at the turbo. Of the Turbo I have rebuilt I have increased fuel mileage by 30 percent. If you want the details of how to gain the extra mileage post a comment to me or ask this question and I will get back to you for the procedure.
YOU HAVE A AIR LEAK IN THE TURBO SYSTEM CK HOSE'S MY 2006 3500 SPLIT THE HOSE HIGH WHISTLING SOUND. LOW POWER / AND LIMP MODES TOO. ORDER THIS AND BINGO IF FIX IT . YES THE OLD TURBO RESONATOR HAD SPLIT TOO. I did not use the o-ring from the old part I found one 1 side down that fit tight around the new part. A loose o-ring is going to weak air too. Got mine on ebay.

yor turbo is sucking it through intercooler check to see if intercooler is oily when you take off hose if it is, then disconect tappet pan hose from torbo intake driveand see make sure to put intercooler hose on back . if oil is still going you have back presure or turbo needs repair
