Diesel Fuel Injection System Help Desk

[dysdamon]

4M40 injection pump is gear driven (no timing belts or chains). Lube oil could be pulled in from the pump's drive end if the drive shaft, oil seal, and/or bushings are worn out. Oil sucked in by the injection pump will return flow to the fuel tank. Result is a dark and thick appearance of diesel fuel due to oil contamination, and seemingly high oil consumption.... These were your initial complaints on your previous post...

So even if we do the top overhaul the problem with the injectors sucking air will still continue? and the fuel tank will still be contaminated with oil?

I do not see how a faulty injector/s will affect transmission shifting when cold.... There is just no connection..

So its a different problem all together, nyikes.

I'll update you sir on the developments though I believe the injectors still needs to be shipped to central diesel for evaluation.
