    I talked to a guy the other night who said he'd had to replace his 6.5TD three times because of getting anti-freeze in the oil. Has anyone else run into this - is it common? Just what I needed - something else to worry about. If it is, is there anything I can do that may keep this from happening?

    You would think after 2 times he would find the problem. While the 6.5 does not have the best rep out there it is not that prone to failure unless it's beaten and not maintained. But that would happen to anything. The injector pumps seem to be the biggest concern.

    Mick,that is a veryu common problem. I have seen so many 6.5's replaced at my local dealer,most of them had under 10K when the motor went bad. I knopw of 3 of them that the head bolts have snapped off,by the time you know it, the oil is full of antifreeze,and the engine is gone.I wouldnt owrry about it,just drive it,if it goes deal with it. The early 24V cummins with the #53 blocks are known to crack,on the pass side between #4and #5 cylinder. If its going to happen you cant do anything about it.I didnt even bother to see if I have a #53 block, Its suck a small percentage of the trucks,its not worth getting worried over. Mick,if your 6.5 needs replacing I suggest a 12V Cummins swap.:D .

    It is a common problem on some 6.5's.I wouldn't worry about it unless you really think you have a problem.An oil analysys would tell you what shape your motor's in.
