i have a good friend of mine thats having trouble with his 7.3..its a 99 F-350 work truck so bone stock..he noticed the oil was a little low so he topped it off and went made a few errands and when he came home he decided better check the oil level just to be sure and noticed it was down 2-3 quarts in about 40 miles so he thought strange and called his knew whom is a Caterpillar mechanic and he said must be the O rings are bad on the injectors so as they pulled everything apart they put new o rings on and change oil and also the fuel filter only to dicover the fuel filter housing is full of oil and upon further inspection the fuel tank contaminated also..so it appears the oil is leaking into the fuel system,any thoughts as to what is causing the problem?
also changing the O rings didnt change anything..
