    Sick 135 hino

    been a few years coming, one hino will only turn 2550, I had the prop reduced in pitch 2 yrs ago and it helped, you can not hear the turbo on this motor, the turbo turns freely , when the said motor is run full power in has dark water coming from exit pipe , not clean water, when I back off the water cleans up, so the turbo is not working, it also runs hotter than other motor, does any one think I have a blockage in the riser were the turbo does not have the exust flow to make it work ?

    It could be a chunk of carbon keeping it from turning. It does not take much interference to hinder operation. Blockage in the riser is also possible. When was the last time the turbos were serviced? Is there a clear path for oil return as well?

      I think...

      The dark water is probably partially burnt fuel.

      This is where a boost gauge would come in handy. Your turbo Might be the problem, or one or more injectors Might be the problem, or a cylinder not making power due to any other reason Might be the problem.

      If it were my engine I would start by measuring turbo boost pressure.

        I know the turbo is not working to its top performance because you can not hear it, it does turn freely , and yes Kevin the gray water at full power is un burnt gas. turbo or riser is the big question??

          Earl says Riser, but at $1,800 to find out I am a little shy
