806 oil leaking around injector

Larry B 1486 · Apr 28, 2009

I posted about three or four days ago about my 806 leaking oil around the #5 injector and one suggested it might be unburned diesel so went back and looked again. It is motor oil not diesel. I washed everything real good so I can see for sure what it is and when I start the tractor, there is motor coming up around the injector. Is there oil around the injector tubes in the head and maybe the tube is cracked and oil coming from there?????

NO ya have a bad seal and it may look like motor oil it is not . Ya need to pull that injector and clean the cup with a injector bore brush till it is nice and clean and install a new seal and clean up the bottom of the injector and reinstall it and torque it in correctly and all will be well.
