Hey everyone this isnt my first time on but i have a big issue on my 6.0 diesel 2004 f250 sd i seem to mix diesel in my oil i drain out about 25 quarts in about 1000 miles give or take and i already payed a shop to replace the seals on them but it still does it i also get a heavy smell from the engine of diesel when i drive but the shop told me they cant figure out what specific injector it can be and recommend i replace all at once or either one at a time so my question how can i know for sure where the leak is coming from? and if its an injector seal or cracked nozzle from what the shop said another question if it is the injectors i was thinking warrens 155cc but either the regular nozzle or 30% over nozzle or even the 175cc idk help guys what to do?
