Hi there:
You didn't specify how many miles or even what moto. Blue smoke appears mostly at morning start up because oil from the vehicle's engine is mixing with the gas inside the engine's combustion chambers, then burned together with the fuel from the injectors while the engine is running. This can result in a very expensive repair, but not always.

The more expensive and usually terminal reason for blue smoke is the piston rings have worn out allowing engine oil to pass into the combustion chamber.

Hope this helps.

Just bought a 2002 toyota avalon with 100000 miles. it blows blue smoke from tailpipes during a cold start. when it it warmed up and i try to start it, it's fine. the toyota dealership told me they are...


Hi There,, with regards to the blue smoke when starting the engine from cold but none when warmed up, it could be the valve stem guide oil seals. you may need to remove the cylinder head and lap the valves in again but it should last you another 100,000 miles.

Blue smokes come out tailpipe when i start the car but stops afte


Helllo there
Symptom: Gray or blue smoke from the exhaust. You notice gray smoke coming from the exhaust when you start your car. The smoke may or may not disappear after the car is warmed. If it is, it is less noticeable. The smoke may have a bluish tint to it. Possible causes:

  1. The engine's piston rings may be worn.
    The Fix: Replace piston rings. (Generally not a DIY job)
  2. The engine's valve seals may be worn.
    The Fix: Replace valve seals. (Generally not a DIY job)
  3. Damaged or worn valve guides.
    The Fix: Replace valve guides. (Not a DIY job)
Symptom: Engine uses more oil than normal, and there is some smoke from the exhaust. The oil level is low between oil changes. It appears that the oil is being burned by the engine because of the smoke in the exhaust. You may or may not notice the engine doesn't have the same power as it used to.
Possible causes:

  1. The PCV system is not working properly.
    The Fix: Replace PCV valve.
  2. The engine may have mechanical problems.
    The Fix: Check compression to determine engine condition.
  3. The engine's piston rings may be worn.
    The Fix: Replace piston rings. (Generally not a DIY job)
  4. The engine's valve seals may be worn.
    The Fix: Replace valve seals. (Generally not a DIY job)

1997 Saturn SL1 very hard to start


jlwhelen,
I will suggest that perhaps the blue smoke is not purely oil. It sounds like you may have an ignition problem where the engine has a hard time firing until warmed. The blue smoke may be, at least in part, unspent fuel. I realize that a warm engine that uses oil will smoke blue, but excessively rich conditions on startup can result in a similar effect. If the choke circuit is delivering a little extra fuel from a dirty injector, the problem may be worse when starting from cold.
To remedy this, I would suggest a simple replacement of plugs and wires, as well as a fuel injector cleaner through the tank. I would bet money that these simple maintenance points would solve your problem.

Good luck!
Lucky

Smoke


If the smoke is blue and goes away after it warms up and the engine runs fine. It's most likely your valve guild are worn, they are common to let oil run in to the piston chambers when the engine has been parked for a few hours and most notice when parked over night. Nothing to loose sleep over, good luck

Nissan 300zx starts smoking when reaches tempture


sounds like your rings are leaking oil into the cylinder.. causes blue smoke. would not do it until it is warm due to the higher viscosity of the oil at cold. try some ring seal and see if that reduces it.
