I have a 2.4 liter MB diesel engine that has been overhauled, but still lacks normal power, and is well past break-in mileage.
Here's what was done: cylinders honed, (re-boring not required) new rings, bearings, valve job, and new filters, timing set properly, compression normal, excellent oil pressure, and starts instantly after glowed. But the engine is sluggish in performance. I have reduced the equation to either a weak fuel injection pump, bad, worn, or wrong fuel injectors, but the engine runs smooth, (maybe partially plugged injectors?). With everything else checking out; I assume it has to be lack of fuel delivery to the cylinders?? The transmission/drivetrain is normal also!
I have two of these same vehicles, and the other one has normal power!
Thanx in advance for your suggestions. The actual mileage at overhaul is unknown.
