Hi my name is***** will be glad to help. What do you have for fault codes?
Engine make/model? Mercedes/Detroit?
No codes I would start by changing the fuel filters and check for restrictions and leaks between the tank and pump as well as verify your fuel supply pressure is good
Check for air cleaner restrictions and for leaks in the turbo and intake boost piping
Check the turbo as well that the compressor wheel is free from damage and spins freely
Thanks for the update. This is immediately after overhaul the low power? You only replace the oil rings and not the compression rings? Any particular color smoke?
My other questions? What work was done?
So you had the head off and reused the compression rings, rod and main bearings etc but there is new oil rings?
That is not common practice. An in frame at that point is. Were the liners honed, measured with a bore gauge?
If I am understanding this correctly and this is the case, the rings are likely not seating properly.
Also verify your valve and injector adjustments are in specs as well. Keep me posted.
thanks for the clarification on what was replaced... as far as the rings... and assuming you reused the original liners did you measure them with a bore gauge and hone them?
