Injector O-rings went

[Dieselpwrdredneck]

They got as bad as letting oil back into the fuel rails and system, the fuel in the bowl was black and that puzzled me along with the sudden dissapearance of large amounts of oil, so low and behold bad o-rings, to my knowledge they have never been changed, i guess 186,000 is good huh

Yep! mine did the same thing at about the same milage. I lost 8 quarts in 150 miles (right after a fresh oil change too). Cheers!
