Ring or valve issue check that the valves are all working and not stuck open, if theyre good take the head off and remove the piston, it will probably need a piston ring and sleeve.

Engine started and was smoking very bad but wouldn't stay started now it won't start at all but will turn over.


The engine was smoking very badly? Was any smoke coming out of the tailpipe? If not, either the exhaust manifold is broken or off the vehicle, or the exhaust pipe is broken, has a hole in it, or it is completely missing! Is it really loud?

You SAID the engine was smoking. But if you said that in error, then perhaps the exhaust system is okay, but oil is getting into the cylinders. Check for a PCV (positive crankcase ventilator) valve that may not be working right. Another thing that can make heavy smoke come out of tailpipes is a head gasket leak, with antifreeze getting into the cylinder chambers. How is the oil level and the coolant level? If there is that much smoke, it is advisable to not drive the vehicle for any reason except an emergency!

Causes for excessive fuel consumption in caterpillar D398 Engine


V12 twin turbo with 2x 6cylinder injector pumps.

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.

Why is my 2000 kia sephia blowing blue smoke from the tailpipe. it has 86,000 miles. the check oil warning light is on even though the dipstick reads full.


The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. This is most frequently seen in older or high mileage cars with worn seals and gaskets. It only requires a very small amount of oil leaking into the cylinders to cause excessive blue exhaust smoke.

Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise. An external engine oil leak can drip onto hot engine and exhaust parts causing what appears to be blue exhaust smoke. Other possible causes of blue exhaust smoke include: piston wear, worn valve seals, a dirty or non-functioning PCV valve, worn piston rings, an intake manifold gasket leak, worn engine oil seals and possibly even head gasket failure.

Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. In addition, a reduction in power and oil loss can be indicators that the blue exhaust smoke is caused by an internal engine oil leak. Internal engine oil leaks can also allow fuel to mix with the oil in the crankcase which will degrade the oil and prevent it from adequately protecting the engine.

Operating a car with a severely dirty oil filter, air filter or improperly functioning PCV valve can also sometimes result in engine oil blow-by, oil loss and blue exhaust smoke. Periodically checking the engine oil level with the oil dip stick will indicate if there is excessive oil consumption. Higher viscosity engine oil can sometimes temporarily reduce the amount of blow-by; however, this is not generally recommended. Excessive blue exhaust smoke indicates a possible internal engine oil leak that should be inspected by an ASE certified mechanic.

When i turn on my 1983 buick regal it starts smoking from behind the motor some where and i cannot figure it out. what could it be?


Oil. if the smoke is coming from between the engine block and the firewall then its probably oil on the exhaust manifold. Make sure that your engine is not leaking oil from the seals and make sure the oil cap and dipstick are in place, start your car, with the hood up and observe the smoke if its bad then id take it to a mechanic but if its only mild then providing your engine isn't leaking oil it should burn off within a few minutes of the engine being started, i say watch the smoke because if it is leaking oil onto the exhaust in great amounts then it is possible it could catch fire.

Car is smoking very badly. All of the sudden.


If the smoke is white is burning coolant, and might be a bad cylinder head gasket. If smoke is blue, is burning oil. This might be valve guide or something else. If the smoke is coming from engine compartment, fluids might spill over exhaust manifold. Hope this will help to narrow the problem.

Volvo 850 smoke coming from exhaust manifold


Not to worry. Run the engine up to operating temp before jumping to conclusions and let the heat burn off any excess oil. A leaf will not do any damage.Do not let the engine overheat while idling and if the oil light comes on switch off immediately.
The smoke from the exhaust is oil deposited by oily assembly hands just burning off. It should dissipate after about 15 minutes at most.(or 5 miles' drive)

White smoke coming from the muffler, loud noise...


One potential cause is too much gas. It may be running "rich". Your car may also be burning a little oil. White smoke is water or antifreeze. If you are loosing coolant from the radiator, it's probably a blown head gasket. If not, it is just condensation in the exhaust pipe that is evaporating as the pipes heat up. If the car is running too rich, the unburned gas will cause black smoke and burning oil smoke will be blue.

Hope helps (remember rated this).

My 1995 olds royal 88 has blue smoke coming from engine area


Blue smoke is oil and if it's coming from your engine compartment most likely means the gasket on your valve cover either needs to be replaced or it could even be as simple and needing to tighten the valve cover bolts a bit. Oil is leaking from the valve covers and working it's way to your hot exhaust manifold and that is where the smoking is most likely coming from.

Oil dripping from exhaust manifold


Either the cylinder head is cracked or, Is it possible that a stud had once been broken off in the hole(s) and when they were drilled out the drill went a bit to deep and punctured the cylinder head? That is about the only reason their would be oil coming out of the manifold stud holes as the holes are not connected internally to anything.
