    Yesterday I was getting my oil changed and they found this in my oil pan. The freightliner mechanic thinks its bullgear and i need to change it asap. he said i am running on borrowed time. My personal mechanic thinks its my compressor ( since its leaking oil bad anyways)

    what do you guys think??? how bad is this and how soon i need to change this?
    bull gear is 800 but to change it its going to be at least 2500$ in labor costs.

    the truck is 2003 freightliner century with 12.7 ltr detroit . 855,000 miles IMG_20140228_134755827 (2).jpg

    IMO, best way to know for sure, is to get a rebuild kit for the compressor, and inspect the bearings, if you don't find a bearing that looks like the owner of those rollers, then you may be on to the bull gear. But it's definitely good to start with come thing you know needs done and less costly, than to go for the big item and be wrong.

    If the air compressor spit those parts out......it wouldn't be just pushing oil.

    I'm not a detroit person, but I'd say the Freightliner mechanic has a vast knowledge of Detroit engines. I'd take his advise, because a total bull gear failure, becomes a rebuild.

    You can pull of the cover for the cam and turn the motor looking to see the bull gear, you can pull the air compressor and look and feel the bull gear. Either way it only costs a gasket to be sure.
    What ever you do running it is not going to get cheaper to fix.
    Just a thought!

    1st replace or rebuild the compressor but pull it apart. They are simple machines. Just a piston, rings and valves. Be sure and save the little coke can thick dime size valve. We used to rebuild them in the field on bullwagons and it only took about an hr., even made valves out of coke cans.

    was told by a 25 year detroit mechanic at williams that I needed a inframe due metal in oil & coolant in oil. turned out to be compressor on the coolant in the oil & the bull gear BEARING on the metal. after over 2 weeks downtime & a lot of money, I still had both symptoms. then they changed the compressor head & that solved the coolant in oil. ran a month then put bull gear in & solved the metal in oil problem. the only reason I did not mind as much as some might on the misdiagnosis is the engine had over 1.3 mil miles, so it was time for some peace of mind having this done reguardless.

    i dont have my pics, but mine looked the exact same

    it was scored metal from my crankshaft and bearings, either from wear or low oil

    i had to get the whole thing rebuilt (good for tax write off, bad for wallet)
