SOURCE: thick blue smoke. no oil

Hi! Chris, There are many causes of oil burning or exhaust smoke. There are three different causes of normal oil burning, 1; worn valve guides (smoking during deceleration), 2; worn cylinders and piston rings (smoking during acceleration), 3; split or worn out valve seal, or damaged intake manifold gasket (smoking all the time). Of course there are several variables in this equation. Sometimes coolant can also get into a cylinder and cause a blueish smoke. If you remove the spark plugs and use a pressure pump on the coolant system (radiator), coolant should leak into the intake manifold or cylinder. Coolant leaking into the intake manifold will leak into several cylinder through the valves. So, what year and how many miles are on the Jaguar?

SOURCE: Stalling and black smoke

Your truck is fuel injected . Black smoke indicates a rich fuel mixture. This could be caused by numerous items. A faulty sensor, a faulty injector, a misfiring spark plug are some of them. To really zone in on the problem, a computer diagnosis is required to note sensor readings, and repair as necessary.

SOURCE: blue smoke

Chances are if you are blowing blue smoke, you are burning oil.  Another cause of blue tint smoke is you are burning to much fuel and not enough air.  If the engine does not act erratic or acts like it is flooding out, then I would say you are burning oil.  The most common problem found with burning oil is either worn piston rings, bad valve seats/seals.  If the engine has high mileage, I would recommend any type of oil treatment.  Change your oil, filter included, use some form of engine treatment, run it for a few hundred miles, and rechange your oil and filter again.  If your engine has over 100,000 miles, I would highly recommend using an oil that is made for high mileage engines.  As this oil has additives that will help ease the aging engine.  If this doesn't work for you, I would say you need to have the rings and valve seals replaced.  You can do this yourself with a little knowledge of engines and pick yourself up a Haynes Manual at your local auto parts store if you do not already have one.  Hope this helps.  Feel free to comment if you need more assistance.  Please don't forget to rate.  Thanks!

SOURCE: emits smoke little blue when stats and stops after

So upon startup the car has a little smoking going out the tailpipe? Then it goes away after the car warms up a little? You probably have stuck piston rings and are burning oil at first until the car warms up and the rings seal better. What kind of oil are you using? What weight is it? I don't know what is in the car, but if it is conventional oil at 10w-30, try changing it to synthetic and using 5w-30. I don't know what that car comes with from factory or calls for, but in my experience I've stopped oil burning in a piston engine with thinner, synthetic oil. This helps to unstick the rings allowing them to seal better AND the thinner oil doesn't collect on the rings so much, keeping it from burning or going out the tailpipe. Also, synthetic doesn't burn and carbonize like convention oil (dinosaur juice) does.

I really hope I understood your problem and helped you with it. If not, please clarify. Good luck!

Have LT 1536 . Smoke started coming out the exhaust but engine sounds healthy

Depends on the colour of the smoke.
Unlikely an engine will sound healthy emitting black smoke - excess fuel.

An engine could sound healthy emitting white smoke (steam from coolant) but not from white smoke (excess unburned diesel).

Most engines emitting blue or blue-grey smoke from burning engine oil can sound very healthy.

My Nissan na 20 emits blue smoke upon acceleration

Seems it may be burning oil. This is common on high mileage vehicles when wear and tear on the piston rings will allow the passage of oil / oil vapour from the crankcase past the rings and into the combustion chamber. Same with worn valve stems and guides.

2005 Nissan Path:replaced batt, alt, plugs, coils due to rough run & smoke. 1st smoke was blue after new parts it's more gray or white. New plugs smell like fuel. Exhaust is rich in fuel smell. Ideas?

Blue/grey smoke is typically engine oil burning.

Grey/black smoke is typically excess fuel (or insufficient air).

White smoke is invariably water that has turned to steam. (water is a natural product of combustion as well as the stuff the head gasket keeps out of the cylinder).
Sometimes an engine can emit a fine mist of unburned fuel that seems like white smoke.

Clearly your engine is burning some engine oil. Perhaps the valve stem oil seals are failing. When an engine noticably burns oil it must be realised this isn't good for the oxygen sensor and catalytic converter and it is inevitable the life of these things will be shortened.

It is doubtful the replacements you have so far carried out will have changed anything and it is likely to be coincidence the colour of the smoke has changed.

What is needed is a diagnostic check to inspect the live data from the sensors when it will probably be found one or both oxygen sensors will need replacing and perhaps other things have grown tired too - at an extended mileage an injector could start dribbling or the spray patterns be so poor the engine won't be able to burn it all and then it will be expelled into the exhaust.

My nissan terrano emits black smoke and uses a lot of engine oil

either the valve stem oil seals have gone which means oil is trikeling into piston thats causes black smoke or worst case oil rings on pistons gone but the smoke will have a bluey tinge to it also may just need a service and tune up hope this helps ivan

Hi i have a 1999 nissan pick up,it has the na20 motor,2l 8valve,my plugs keeps on getting oil on them,by that happening it kills the plugs.anybody know why this is happening?ive drained the oil and found...

Do a compression test. You may have bad rings. That could allow oil inside the cylinder and fuel into the crank case. I don't know what the compression should be but all cylinders should be the same if not very, very close to one another. If one shows 100psi then the rest should show the same.

94 Jaguar xj6

The jag 6 cylinder does emit white smoke on start up generally, its condensation being burnt. However, if it is excessive, you should check to see if you are losing coolant. Then its a whole new ball, game. Black smoke indicates excess fuel being burnt or lack of it , ishould say and blue smoke indicates oil burning.
Hope this helps
