    I've got a 2007 Western Star with a Detroit 515 in it. Putting antifreeze in it every few days. No leaks have been found. Do have some white smoke and a bit of loss in power. Oil cooler replaced and pressure tested, no leaks. There's a slight antifreeze smell when I turn on the bunk heater.

    Any additional smoke when you start it after siting for a while? I had an EGR cooler start leaking a few years ago, white smoke on start up, burned about half a gallon of coolant a day heading back to the shop.

    Yes but just checked the oil and it's sludge. Could that be head gasket?
    Hoping I won't need an overhaul.

    There is a few things that it could be but a shop will be able to tell you for sure and not be guessing like we would be not being able to look at it ourselves

    Sounds like you need to trace the heating/cooling system into the bunk. Sounds like that's where your leak is coming from.

    I am wondering about your fuel mileage. I do found a 2006 to buy, 18 speed, 515 HP also.
    Also, is it ok to find loads , as O/O, with that truck age?
    Thanks
