rightsaidfred Posted September 14, 2014 Share Posted September 14, 2014 Did an inframe on a 1976 R-600 (maxidyne engine, ENDT 676). The old turbo was pretty tired, but put it back on to wring a little more life out of it.The turbo immediately started pushing A LOT of oil out the exhaust side; like a gallon an hour; it smoked like it too.Put on a re-built turbo, and immediately it has the same problem. ??? The oil return from the turbo is free and clear; oil pressure is as it was before the rebuild; otherwise the trucks runs good. Quote Link to comment Share on other sites More sharing options...
theakerstwo Posted September 14, 2014 Share Posted September 14, 2014 Remove the turbo and cap the oil pressure line and then run for a while and see if the oil is coming out of the manifold.May not be the turbo. 2 Quote glenn akers Link to comment Share on other sites More sharing options...
gearhead204 Posted September 14, 2014 Share Posted September 14, 2014 yes do as Glenn said, very rare that a turbo pushes oil out the exhaust side.! Quote Link to comment Share on other sites More sharing options...
