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.

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 https://www.bigmacktrucks.com/topic/37074-big-oil-leak-on-turbo/#findComment-259723 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 https://www.bigmacktrucks.com/topic/37074-big-oil-leak-on-turbo/#findComment-259736 Share on other sites More sharing options...
