Hi everyone I got go done overhauling my D4 2T. And now after the overhauld went to fire the old girl up and was a no-go. I had to get a new head for the old girl fter the exhaust valve broke and bent the intake valve and beat the heck out of the top of the pistion. The head is a brand new head with nwe valves,springs, precups and all new seals and gaskets. Put the D4 all back together and went i went to fire it up nothing. It will fire on either but that is about it. I have white smoke from exhaust but will not run. the fuel rack is moving and plungers are al moving up and down in pumps. I m not sure if when i took the injector valve apart i might have messed up the adjustment of them and thats what is stopping it from firing up. I put in all new rings and replaced the messed up piston. Im unable to run pony motor for a long lenght of til because it will start to overheat the pony when i open the vent on the manifold assembly it start to get steam out the the airbleed vent after running for 3 to 5 mins. i removed the ponymotor and cleaned out all the water passages on the bottom of the motor and the heads and block and back flushed everything really good and still wants to overheat. must have water leak someplace after running the pony twice the oil was milky white. I have anthor pony motor to put to but needs ne connecting rod and new .10 rings. pony was pulled from machine and replaced with current pony off of my parts D47J. Any body have any ideas what im doing wrong or where the water is comming from?
