There is nothing wrong with your car, the color of the smoke is a sign of good combustion.

SOURCE: 1993 TOYOTA TERCEL 1500cc Valve Seals Replaced now smokes much worse

You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.

When starting toyota fortuner 3.0 liter blowing blue smoke what is causing this


It is oil smoke. The most common causes are worn valve guide seals, a faulty PCV valve, or, worn or broken oil control rings on the pistons. Only 1 or 2 cylinders need be at fault.

Check the PCV valve for fouling. Have a compression test done. If readings are low or irregular, pour a few ccs of engine oil into the suspect cylinders thru the plug holes. If compression readings then improve, it is probably the rings at fault.

Less common causes are worn big end bearings spraying excessive oil up the cylinder walls, or a leak from the head gasket, oil to cylinder.

Smoke engines


Smokes can be of three colors.
1. White smoke.
Excessive white smoke reveals presence of water in fuel, thermostat valve stuck open, or burnt cylinder head gasket.
2. Black smoke.
Black smoke could be observed due to the unburnt fuel or higher percentage of Hydrocarbons during the combustion process, defective regulating valve, ruptured PCV valve, low fuel pump pressure, defective charcoal canister, ruptured or leaking fuel injectors.
3. Blue smoke.
Blue smoke reveals the engine failure.

My Toyota Quantum 2.7GL idles but does not rev up. i ve changed the fuel pump and filter but still it starts, idles but does not rev up when you press the accelerator?


We do not have this model in US, but I assume it is a new model 2016-17. You throttle (and the "rev" ) is controlled by the computer. The fact that your car is idles - should mean that your computer is fine! There are two types of idle control: 1st- when you have a bypass of the throttle, which lets the throttle flop stay close while idling and let's the air into the motor through a bypass and electronically controlled idle switch. Inspect your throttle - the electronic/metal unit located on the large pipe through which the air gets into the motor: if you have a "bypass" for the air then you need to inspect your throttle body as it could be your problem.
2. most likely you do not have a bypass and your idle is controlled by your throttle body, then it is sure working fine and your only issue is that your engine computer does not know that you press the accelerator. Your gas pedal has an electrical unit on it which connects to the engine computer- inspect the connector/wires if all looks fine most likely your accelerator sensor does not work- you need to change the gas pedal unit ( I think it called accelerator sensor).
Good luck.

Take a compression test on # 4. It may be a little oil burning w coolant getting by the head gasket. POSSIBLE faulty injector or not firing on time. Ck for any oil in the anti freeze or anti freeze in the oil.

My engine management light keeps coming on on my Rav4 (2001) I have had 2 sensors changed - and a new cat - but the fault codes keep saying it is the cat - please help!


The ECU is reporting the cat error code because the O2 sensor(s) outputs are telling it so. This MIGHT be the O2 sensor(s). You say two sensors have been changed, If these were the O2 sensors, then there is another engine issue to fixed.

The usual reason is that the engine is passing excess hydrocarbons into the exhaust, typically because its burning oil due to exhaust valve guide wear or/and worn valve stem seals. For a 2001, you've probably done around 200,000 km, so valve guide wear is likely. A head recondition is the only cure if this is the case. If you see blue smoke on starting, that's burning oil.

Related issue is worn piston rings: also causes excessive oil consumption.

Another problem is leaking (ie dirty) injectors. Most garages can clean them.

Another problem is the engine is running too lean. This can be caused by a dirty air cleaner or any number of other issues.

Have excessive blue or white smoke from exhaust when truck is started after sitting for a few hours 2005 f250 6.0 ehgine


Hi,
is it a diesel or gas engine?
Usually excessive blue smoke on start up indicates oil is getting into the combustion chamber. It could be piston rings or valve seals.
Quick check, drive it within operating range and speed. Either use the rear view mirror or get someone to drive it and you follow in another vehicle. Accelerate, then take your foot of the accelerator. Blue smoke under acceleration indicates piston rings / pistons. Blue smoke on deceleration or the "over-run" indicates worn valve guides / seals.

White smoke can indicate coolant in the combustion chambers / leaking cyl head gskt, or incorrect fueling. If brake fluid gets into the combustion chamber it will generate a lot of white smoke from the exhaust. However, that would entail a leaking brake master cyl and a leaking brake booster.

Good luck.

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.
