my little blue hose dosnt have clamps on it it has the push on type and i a not sure if this is the little hose you allare talking about. it goes from the egr cooler hard line into the back of the oil cooler, will it pull off or do i have to figure out a way to cot it off, by the way the back clamp is under the front of the turbo, any suggestions

 

that hose just pushes into place, there is a flat spot on that metal band that lines up with the arrow on the oil cooler, once lined up the hose can be pushed off or on, if they are lined up now that might be the leak so just give it a turn so lines are not matched up and see if it still leaks.
