Oil makes smoke. Your problem is that the chimney isn't drawing well enough to take the smoke up. Get an air kit to supply combustion air to the burner. This should relieve the pressure imbalance that's keeping the smoke from going up the chimney. Until then, increase ventilation to the room where the water heater is. Open a window or other vent. You'll lose heat this way, but it's better than having combustion gasses in the living space. Get it fixed promptly. This is a safety issue.
Turn the fuel down.
Take an antacid.
Blue smoke is oil burning, White is steam(water), Black smoke is unburnt fuel.
You can stop your 7.3L from blowing black smoke by verifying that it is burning fuel cleanly and make sure the fuel mix is not too rich. You can also verify that it is not burning any oil.
Black smoke is a sign of an overly rich fuel/air mixture, unlike blue smoke which is a sign of oil burning. Seek professional help.
Have your injectors checked or changed, burnng to much fuel
Belching is a natural bodily function from too much gas in your stomach. You can't stop and shouldn't try to stop this. You can try an over-the-counter anti-acid such as tums or pepto-bismal. If it is concerning to you, see a physician.
This is a symptom of acidity and/or frequently changing PH. The body is alkaline with a good diet. If you can achieve this, the belching should stop. See the related links for a food chart to tell you which foods become acidic or alkaline in the body.
no.
turn the engine off
Both Stop Lamps Burned OutSounds like pure coincidence to me.
White smoke = Coolant entering the combustion chamber. Possible blown head gasket. Stop driving Blue smoke = Oil burning from worn internal parts. Black smoke = Overly rich fuel/air mixture. Stop driving and have repaired or you may ruin the catalytic converter.
