Customer Question

Hi I have bought a 97 mazda 626 and runs wonderful - however a cold start on the car causes a lot of white smoke (sorry not really sure the smell) it tends to go away after about 3 to 4 minutes. All fluid levels are okay (they are't overful) have had the car running with radiator cap off and coolant levels stays constant (no bubbles) have even done a home compression test on all 4 spark plugs and all come up perfect.

Customer: Sort of hoping with my dads assiatance to fix it myself
JA: Is there anything else important you think the Mechanic should know about your car?
Customer: The previous owner has put an after market exhust and high performance Air filter on - not sure what difference these would make, ever had a car with these

Is the smoke from the exhaust?

Does this smoke occur regardless of the outside temp?

Are you sure its white and not blueish which would be a sign of leaking valve stem seals.

Thanks for asking your question and letting me try to help you.

the smoke comes from the exhaustOccurs when the car is cold - so first thing in the morning and after work (car has been sitting for 8hours), but not so much if the car is still warm.Can't say if it's has a bluey tinge or not - looks white to me

White smoke would be a sign of fuel not even trying to burnt or condensation, or coolant. If it were fuel from a leaking injector, I would expect it to run rough on startup and your engine oil to be diluted with fuel. Condensation smoke is normal under 50 degrees F outside. Coolant smoke would be a head or gasket failure and you should be losing coolant while running and have coolant in the oil.
