Case excavator lost power due to malfunctioning turbo; be sure turbo has proper oil supply

 Matt found his newest acquisition, a Case excavator always on verge of stalling as he goes through its function.   It happened on  cold day, and he mistakenly had an open throttle, and this may have caused the turbo failure.

The solution is always turbo replacement and the challenge was removing the turbo from the exhaust manifold.  You need heating the nuts and bolts and they can get stuck in areas where there is plenty of cycle for heating and cooling.   

Thus do not turn off engine at once after a long drive as it will cook the oil cooling the turbo.   Install a turbo timer and or wait for 5 minutes before turning off the engine

Black smoke after replacing turbos and injector

 It could be due to the intercooler.   Signs of defective intercooler:   black soot and oil at the underside from the leak.
