One of the injectors was not working to full capacity and therefore
diesel leaked thru the seal and leaked into the
oil. The
oil level rose but the pressure gauge went down due to the different viscosity of the mix. We replaced the injector and almost got back our full
RPM capacity. It will take a bit of time because I fear some glaze has formed. It explained the white smoke,unburned
fuel and the low lub reading, mix of
diesel into the oil.
Thank you for all your help. We finally found out by untying the
fuel to the cylinders and listen to the
RPM change. Cylinder 4 gave almost no change in sound while all the others did.
