My last Volvo truck poured black smoke for months (constant when driving); it clearly didn't have the "normal" amount of power but was drive-able. It was eventually found to have a "thumb-sized" hole in one of the boost hoses from the turbo to the engine and once it was replaced, the smoke ceased (and the power was improved). The engine was an ISX Cummins and it had a shriek/whistle that we never did resolve - I long suspected it to be an exhaust gasket, but it was turned in and retired instead of being fixed.

thats about how it feels and sounds too... since that engine has a doghouse i can hear the turbo spool in.. and yeah its aboiut right.. the smoke isnt coal-thick and is gone once I hear the turbo and notice that extra kick as my tach goes out against the torque converter...
since I cant see the Light smoke I notice in the mirror at night against headlights.. I dont know what color it is.. but its not bad and i never have any blackening on the back of the bus from the exhaust.. so im guessing its not blowing or burning lots of oil.. it sounds good and has good power (for a DT-360) so unless I just drive it... I suppose it could use a little more power on the hills... but I havent gotten brave enough to turn the fuel screws yet... though im sure if I really wanted to make a 65-70 MPH rig i would need to upgrade the transmission from my AT545, then turn the screws on the DT-360...
or I just drive the other bus that goes 65 as it is.. LOL
