Hi I have an 1950 Russel built fish Tug with a oldie but a goldie marine 6 cyl marine diesel I believe it is the 140 HP i have found fuel oil in the engine oil and suspect that the injector tubes are leaking some one before Me put "O" rings at the end of the injector tube where the copper washer is as to stop any leaks but I see the that it really needs new copper washers that I was able to purchase now i would like to replace them and torque and that is my question does anyone know what the torque values for injector tube for the copper washers is while I'm here this engine runs like a top but it smokes a dark grey black smoke when it is operating all the time does anyone have any suggestions to fix the smoke problem if i could stop or slow the grey black smoke down i would be so great full





Thank you very much Murray Smeltzer

I'm guessing he's got a J- Model Cummins.

Hi Murray,

the torque on the injector inlet & drain fuel tubes is 20 to 25 ft/lb using the wrench on the large nut next to the connection springs.

Also only remove 1 x tube at a time to make it easy to re-install.

Black smoke on those old girls is usually a sign that the injectors need adjusting. This can also contribute to fuel in the oil as well due to a slack injector set.

If you need help with how that is done then just holler but the settings are Injector @ 48 in/lbs Intake .017" Exh '027".

cheers,

Newto
