My dad has an 02 7.3 powerstroke and he is losing 6 quarts of oil in about 600 miles and we cannot find anywhere where he is losing it? The exhaust is clean, just passed emissions, the garage floor is clean. No leaks that we can see. If it was leaking out the bottom that much we would definitely create a spot on the garage floor. Any ideas or help would be greatly appreciated. Thanks -Adam

 

Have you looked in the atifreeze and behind the or under the fuel filter on the high pressure oil pump there is 18mm plug that has a oring around it can leak there you can take a flashlite and look on top of the motor behind the fuel filter and see if you have oil there.

 

6 qts in 600 miles?!!! wow ud think u could find something that bad

 

its going into your fuel tank bet you got a leaky injector oil leaks past the orings and at the psi the oil is at it wins then it forces its way into the fuel tank via the fuel return line

 

My buddys brother had the same problem and he had a bad turbo. Good luck!

 

huh he already said the exahst was clean so no bad turbo?
