99 powerstroke loosing oil.

[mtmckiddy]

My 99 with 200,000 miles went from using no oil to using a gallon in 1000 miles. I don't see any external leaks. Could it be turbo injectors or something else?

check your antifreeze and see if thats where your oil is going. if your antifreeze has oil in it your oil cooler is bad.either your seals in the oil cooler are bad or your oil cooler is rusted out on the inside.

sorry if this is the wrong place (maybe should have started my own thread) but how can you tell the differance between oil or diesel in your coolant?
