I have a Ford 4000, 4 cylinder, diesel, general purpose tractor. It puffs white smoke on startup and any time the throttle is advanced, even when it is advanced by the governor. So far, I have:
1. Drained the fuel tank and put in fresh fuel
2. Added a high priced Barr's head gasket sealer to the radiator
3. Timed and checked, rechecked, and rechecked the injection pump timing. It is set to 18 degrees BTC, without any doubt.
4. The coolant level in the radiator is not going down and there are no bubbles or foam in the radiator.
5. I cleaned and refilled the oil bath air cleaner and even ran the engine with no air cleaner on it, but that made no difference.
6. I replaced the two umbrella seals and the O-ring on the injector pump drive shaft, plus the large O-ring on the end of the shaft that mates with the engine block when the pump is installed. I replaced these seals because the oil level in the oil pan was growing when I ran the tractor. It is no longer growing. I changed the oil and filter and the oil now looks perfectly clean.
7. Replaced a couple of fuel lines whose ferrule nuts were screwed up.
8. I can hear the engine surging slightly when it is idling. The tach shows a variation of maybe ten RPM.
I'm flummoxed. Any ideas of what I should do next to fix the white smoking?
Thanks for any advice.
