plugged my 6.0 ex up night before last around 530 am, outside temp 38 degrees in south carolina. went out to crank truck before leaving and had abot an 11 in damp spot on driveway and could see collant dripping from arond where my heater is, know it was collant because i am running cat brand elc (red). after truck warmed up leak stopped, looked like it was leaking just above heter element off of a metal tab on the block. put on lift at dealership today and was told it was probably leaking around the blue hose at the egr collar and running down off of back of engine. ?#1, do the blue hoses leak. ?#2 does this make sense. ?#3 is there somewhere else i need to look for a leak around this area, gotta find t before i can fix it, would like to do delete and oil cooler but money tight near xmas, ANY ADVICE GREATLY APPREATIATED..
