SOURCE: Combo diesel engine blows blue smoke from only one

Blue smoke means that the cylinder is burning oil with gas/diesel. White smoke means that the engine is cold and excess fuel is being burnt. It means that the cylinder is having worn out rings.They need a change. Also check the engine oil level as well. It may be going low gradually.

I have toyota hilux 2.5d4d 2kd engine it smokes allot blue smoke an engine shakes allot what can be problem


if there is a lot of blue smoke its burning engine oil and the shaking is because the plugs are not firing correctly because they are fouled by the oil. also could be plug wires worn out, distributor cap and rotor if it has one as you don`t say what year this is. the burning oil could be rings, valve seals/guides, PCV system plugged.

What could blue tailpipe smoke be from?


Your issue could be a few things. Simplest first would be the PVC valve. Other issue would be valve seals, valve guides or piton rings. The blue smoke is from your vehicle burning oil

Hi. I have a 2006 Toyota Hilux with a 3.0 litre D4D diesel engine. It blows out blue oil smoke for about five seconds on startup. If I perk the car on an upward facing smoke the problem is worse. If I park...


Hi , couple of questions,
1. is it using engine oil?
2. What type of diesel fuel do you burn ?(cheap/premium)
3. Have you ever used fuel additives ?
4. Does the smoke go away after warm up or still there when you put car under load / accelerate hard?

Simple thing first with the engine ticking over lift bonnet/hood and remove the dipstick, have someone lightly rev the engine LIGHTY if you see oil traveling up the dipstick spout , this is a sign of the crankcase pressurising , their is a crankcase breather filter which are obtain overlooked during servicing which can cause e
If you are not burning oil , look for the egr valve it will be coming off the air intake and insure it is clean and operational( this is an emission saving device fitted to diesels which lets the engine re -burn it exhaust gases) it can get clogged with oily residue from the diesel fuel and in fact can be like a tar consistency this clogs/ not functioning correctly can cause power loss and oil deposits making their way into the exhaust system and stops valves seating correctly . On positive it is easy to work at and clean with brake cleaner, then dry and lightly oil to free up then wipe clean.

also worth while and to ensure work on egr was worth while and lasts remove the air intake ducts as these too will be clogged it builds up over time and can reduce the air duct flow by50% this is not cleaned during ordinary servicing! clean with boiling water and washing up liquid sounds strange but worked best for me! Let sit to work using baby bottle /pipe cleaners when clean ensure it is dry completely before refitting I found blowing out with compressor was worth while as you do not want and loose dirt inside as I will make its way through.

final thought which has been very beneficial for me, when carried out the above use only premium fuel( cheaper fuel now is mixed with bio diesel and leaves bad engine deposits ) use diesel fuel additive I have found millers Eco max 4 excellent, double dose first time drive hard in 3rd for a few miles to work its way though you will notice smoke for the first couple of used this is contamination working through system. Let me know how you get on and good luck.

Toyota Caldina 1999, too smoke from exhaust


if it is diesel and you have black smoke you need fuel injectors either serviced or replaced also you must check the engine valves clearance. If your smoke is blue white smelling unburned fuel renew injectors.If it is blue white smelling oil and diesel then you will have piston rings and valve steam seals.

My Toyota Surf 1995 - diesel engine is smoking (releasing black smoke on the exhaust). 1. Is there anything I can do to stop the problem? 2. What type of engine oil is better for the car?


First make sure your air cleaner is good and clean. Black smoke indicates lack of air and uncomplete burning of the fuel mixture. I don't like to recommend oil but you should be able to see what the manufature recomends in your manual.
any 15w/40 diesel oil is as good as another in todays world,toyota oil is one of the major oil companies anyway,if you stick to caltex esso shell ,bp any of the major oil producers you cant go wrong ,,even pensoil valvolene no worries Diesel engines require more frequent oil changes due to the carbon that escapes around the piston and rings while operating.

Hi, I own a 3.0 d4d toyota fortuner (same engine as 3.0 d4d hilux) and as of yesterday it started belching white smoke. it starts and idles perfectly fine, the exhaust just smells off. not like unburnt...


White smoke on diesel engines, means water in combustion chamber. Blue smoke means oil.
In what condition was the filter you removed? How bad? Temperature issues? Missing coolant maybe? If yes, you might as well have an internal leak. Some gasket maybe. Check all you vital fluids levels. If anything missing, take the time to empty the engine oil on a can, and check the colour. If it will look like chocolate brown, then you do have a leak from the inside.

White smoke from tail pipe for few seconds


A little steam is normal.
Blue smoke is due to oil burning.
White smoke is due to coolant getting into the combustion chamber.
I recommend checking the coolant, and oil, if both are okay, you could do a compression test to verify how everything is.

Smoke out of tailpipe on startup


ask a question. White, blue, black? its most likely steam on this new of a car. nothing to worry about. if blue, its burning oil, blue on start up is leaky valve seals, black on startup is leaky injectors, real white smoke (tons will come out) not steam, is blown head gasket or cracked head/block
