    Sounds like a good reason to open up the
    Freightliner Emergency Repair Kit.

    Sounds like injectors are going bad.

    If your going to run this truck at all I would drop the oil and add two gallons of Lucas oil stabilizer to it. Might help prevent any more damage till you get it fixed.

    Yes that what he is talking about. When buying a used truck it is a good thing to change the bearings so you can know what you're dealing with from the start

    I had Injector selinoid leaking on mine. Fuel is oil only thinner. Should be fine. Ran mine till it shut down . Had 10 gallons of fuel added to oil in 60 miles!! Thought I had just blown injector as in the past. Anyway common problem all’s really needed is 1 new. Or buy a six pack for same price as 5. Mines still going good after 1.5 yrs. and mine has over a mil on OH.

    Oh yeah I had 10 gallons of diesel on top of 10 gallons of oil. Only permanent damage was rear main leak got worse. Front main seeps ever since. I ran about 10 miles changed fuel filter same problem, decided to make a run home ran 63 more miles and it shut down. I figured it was a bad injector. As it was running rough. Didn’t think about it leaking into oil like that.Exact same engine as yours. The plastic selinoid on top of injector was squirting a lot of fuel. That might be your problem especially if it was running rough.You didn’t mention that though. Could just have a minor leak. Sometimes the little screws on selinoid come loose, usually they break. I bet 1 screw is broken off 1 injector selinoid causing minor leaking.Ofcourse it could be a bunch of other things I’m sure.Let Us know either way. Always looking for potential future problems.I only changed the one injector. Had 1 go bad a few yrs back also. That time it was just a bad o- ring causing excessive fuel into cylinder.Cost for Dealer to install 6 pack was $3000. Decided to wait and apply $$ at OH. Old Detroit still running good. They can take some abuse. I doubt the bearings are damaged ( maybe a little more worn ).I don’t know what you’re mileage is or OH or? Mines currently got 1.3 mil + on an OH. I really can’t believe it myself. I’ve never pushed 1 this far.

    It's 700 for an injector. Or 12k for a rebuild. Use your brain. I know you put it in the shop. Hopefully it's cheap.
