My toyota d4d hilux double cab is emitting black smoke


Black smoke is usually excess fuel, that can be caused by things such as leaky fuel injectors, bad coolant temp sensor, weak spark (bad coil?). You don't say what year or engine. If a carburetor, it may need overhaul. If excess fuel gets really bad, it can wash the oil off the piston rings and cause rings to wear, plus dilute engine oil causing bearing failure.

What could have happen to my car i have notice oil inside the Spark plugs what could have happen to my car?


There is always an oily _looking_ deposit on spark plugs if the spark plug was removed after a short run. It is actually unburnt fuel.

Try this, take the car for a good run of say 30 minutes. Come home and remove the plugs hot. The tips should be a straw colour. The hollow cavity is often black.

If they are oily, install new plugs and check them after a week. If they are still black and oily, my guess is that either the bore is worn or the oil scraper piston ring is letting oil past it.

Does it consume oil, does it smoke after idling and then when you boot it at traffic lights?

Ford laser 99 no power


Hi there.
well when you throttle up to about 2000rpm do you get blue smoke coming out the exhaust.When driving on flat road will it power up as normal with out missing or getting hot.
what colour was the old spark plugs were they black or light brown.
When you start engine and run for 3 minutes then let it idle and remove oil filler cap do you get smoke coming out.
Number 1 if yes then engine is lacking power due to piston rings worn answer rebuild engine.
Number2 spark plugs brown [good] if black soot as num1.
Number 3 if you get black smoke or blue ,then the engine is lacking compression could be your problem as num1
OTHER WISE GET YOUR TIMING CHECKED AND SET TO BOOK.

1997 mazda e2000 van which is blowing black smoke


if it takes 5-10 mins of running before black smoke disappear i think you could have broken rings causing engine oil into the combustion chamber. you could observe white smoke if you have just changed oil.
solution would be to replace piston rings. it would save u a lot if u could diy.

Blue smoke


Blue smoke is never a good thing....

Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles.
How did the engine oil get inside the cylinder in the first place? The car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

your engine has worn valve guides, piston rings An engine that burns a lot of oil (more than a quart in 500 miles) is an engine that needs to be overhauled. Normal oil consumption should be a quart or less in 1500 miles. Most newer engines consume less than half a quart of oil between oil changes (every 3000 miles). So if your engine is burning oil, it's essentially worn out and needs to be repaired.
Because the cost of overhauling or replacing an engine often exceeds the value of an older car or truck, many people will just keep on driving a "mosquito fogger" in spite of the blue clouds of smoke it leaves behind. Never mind the pollution it causes, oil is cheaper than a new or rebuilt engine they reason. That philosophy may be okay if you live out in the sticks somewhere. But in urban areas that require periodic vehicle emissions testing, an engine that's burning oil usually won't pass the test because of excessive hydrocarbon (HC) emissions. You may get by on a waiver after you've spent some money (in vain) on a tune-up, but the fact remains you're still a polluter.
An engine that burns a lot of oil will also eventually foul the spark plugs. Thick, black oily deposits build up on the plugs until they cease to fire. Then the engine misfires and loses power. Cleaning or changing the plugs may temporarily solve the problem, but sooner or later they'll foul out again.
Forget about "miracle" oil additives or pills that claim to stop oil burning. They don't. Better to save your money and put it towards a valve job and new set of rings.

I have honda accord 1991,but i found lot oil in one spark plug,what mean thas?


It means that an engine with worn piston rings and/or bad valve seals are allowing excessive oil to enter the chamber.

Changed spark plugs on my 03 maxima and notices that one of the spark plugs was soaked in oil . what would couse this .


it shows that the piston rings of that cylinder are weak and they cant hold the lubricating oil below the burning chamber and oil is burning with gasoline. Check the smoke from the exhaust pressing gas paddle full, if a lot of white smoke appears, u need to replace the piston rings, if the smoke is negligable, u can enjoy another 10,000 kms without any problem but with a little care of not pressing gas paddle in smaller gears, I hope this will be helpful.
