If blue smoke started but then it stopped what does that mean?


When you stop at the traffic lights and then drive off and you get blue white smoke then you have either worn piston rings or worn valve guides where oil is getting into the combustion chamber.

I have a 98 mazda 626 only when its cold i have like a blue gray or even white smoke coming from the exhaust don't know what it could be?


Your exhaust valves have deposits on them that don't allow for a good seal when the engine is cold, or your piston rings are worn, allowing oil to get past when the engine is cold. In either case the seals improve as the engine warms, making the smoke go away. You can try to see if an oil additive will improve your situation.

Smoke on startup mazda 626


If it's the org. engine it will has over 150,000 miles on it.
It's normal to has the valve seal/oil seal on the head to leak oil into the cyclinder.

The smoke you see is the motor oil drop from the seals. It land on the top of the cyclinders and it create black smoke at start up.

The inexpensive fix is to start using high mileage oil with seal conditioner.
This will help soften the rubber seals and help reduce internal oil leak.

The correct fix is to wait until it's time for a head gasket replacement and let the professional service the head.

Complete head service is the only method to stop this internal oil drip problem.

On start up I get lots of white smoke this lasts until car warms to normal operating temperature, car is using a little oil have noticed oil spitting from exhaust, no obvious sign that the head, head...


Stage one of a blown head gasket is a pin hole leak. As time goes by the hole(s) get bigger.
I will start traking the coolant lost and oil lose.
From the time you stop your engine to the next morning,there can be slow leakage between the coolant passage and the cyclinder end of the head gasket.
This is one possiblilty of lots of white smoke in AM.
Small amount is normal but large amount of smoke is a call for a professional check up.
To pin point a blowing headgasket you will need
1)coolant system compression tester
or
2)chemical reaction test for combustion test gas
If it's the org. engine from 1997,with over 110,000 then blowning headgasket is a good possiblity.
Drive it to the shop and let the pro to do the coolant pressure test and combustion gas test.
A full head gasket job with head re-surface (if it can be re-use) is worth it.
Shop around on well estiblished independent shops.
Fix the blown head gasket at the first stage of failure can safe you thousand on a head replacement.

My 1991 mazda 626 runs great but will not stop burning oil and white smoke keeps coming out of the exuast pipe


Hi Arelis,

It sounds like two different problems. White smoke is indicative of water in the fuel. If it was oil burning the smoke would be blue.

The oil may be leaking out. Is there evidence of oil leakage on the road when you park? Check the engine for for oil leaks.

There are additives available at auto parts stores that deal with water in the fuel supply.

Please feel free to contact me. More details will be needed to get to the source of the oil problem
