| Hey guys-We have a 03 International bus w/dt466 that we just farmed out for repair due to only having 1 mechanic & being very backed up..anyway we sent it out for the oil rail gasket.Since getting it back it now is loosing or using substantial oil(15 qts low in 2 days)but there is no sign of external leakage,no oil in the coolant reservoir,and it's not smoking either.It also had an in frame done less than a year ago. |

| Check the fuel tank and see if the oil is in there! If so its one of two things, either the oil rail gasket is on wrong or the injector orings are bad. |

| Thanks for the reply Bus Tech II.We have confirmed that there is oil in the fuel tank.Took the the bus back to the shop & they say we need to replace all 6 injectors but could'nt the O-rings just be replaced? |

Yes there is an oring kit for the injectors. Unless you have and issue with missing, i would just rering the injectors.

As long as the engine is running well, you do not need to replace the injectors. Just the seals.
That said, however, the age and mileage should be taken into consideration. If it's over 100k and you plan on keeping it for a long time it might be a wise investment.
If you plan trying this yourself, follow the draining and priming instructions to the letter. |
If it doesn't fit, FORCE it.
If it breaks, well, it needed replacing anyway.
