Excessive fuel consumption can be ...
fuel leak on to the ground.. Obvious
fuel leak into sump via fuel pump body... Check sump oil
worn piston rings... Grey Smoke
glazed cylinder walls...smoke
burnt valves... Need compressin test
faulty turbo(s)... Sound, check manifold pressures
blocked exhaust line/muffler... Smoke black
faulty thermostat so motor doesn't get up to temperature, what is motor temperature ? ... Smoke black
lack of oil, wrong grade of oil for temperature
scavenge fuel line from injectors blocked or not returning to tank
faulty injector(s) causing poor fuel spray
faulty injector(s) bleeding fuel into cylinders... Smoke black
faulty injector pump balance
faulty injector pump timing
faulty coupling between injector pumps, even can be one 180deg out of timing
bad diesel fuel
Are there mechanical losses in motor load ? Alternator fault ? or gearbox fault prop fault ?
What is the exhaust colour ? Black or grey ?
What are the inlet manifold pressures ?
Using a thermometer ( IR if available ) what are the cylinder head or exhaust manifold temperatures ? This may isolate problem to one or more cylinders.
If you can supply more information I may be able to help track down the problem.
white smoke from the tailpiple is a tell tale sign of a shot head gasket. im not sure how your fuel pump is related, but, if you indeed have a bad head gasket, you could brick your engine with further attempts to restart.
examine your radiator fluid for an oily film, and examine your oil dipstick for any bubbles, or other signs of oil and water mixing- these are often symptoms of a blown head gasket.
you need to clean out the sump air vent. and change the filter for the air breather. some are fitted with a clean easy filter you take off and wash out.
HI, Time to find out why your oil level is going up. Either coolant in the oil, or fuel in the oil. Which ever it is the cat engine is not happy. My suggestion would be to get an oil sample test. Any major diesel repair place will help. Just a little oil in a sterile jar to be analyzed for contaminants. Coolant is the worst as it will scour the bearings. Good thing you are concerned. Wayne
