Just popped a 1HZ with a 5 speed into a 91 FJ80. All is well except for excessive white/gray exhaust smoke at start up and into the first 30 miles of driving. Engine sat for 2 years, however I have run it for 3-4 hours and it still smokes. I adjusted valves, rebuilt injectors, new filter, new air cleaner and still smoke. My question is, could it be the old gas FJ80 in-tank fuel pump causing too much restriction? I pulled the fuse on the pump because I felt the fuel pressure would be too high for the diesel, however I did not remove it from the tank or fuel delivery system. Any thoughts out there?
Thanks,
