Bought a used vehicle, 2 and 1/2 weeks later it is suddenly putting out white exhaust for a few minutes after starting up. The exhaust now smells sickening (to me) at all times, and must keep the windows up; I’ve noticed sneering from others in line at the drive through. I read online that this could be a gasket leak. I checked the oil and it looked clean, so I drove it back to the dealership to have them look at it. They called today to say that “checked the fluid levels” and that there is no evidence of a “consumption issue” at the moment, and suggested I drive it for a while longer and then have them check it again. It came with a 3 month / 4000 mile warranty, and I drive so little 3 months will pass by sooner.
What should I be considering?
Take it to a trusted mechanic and get their separate diagnostic?
I read that antifreeze mixing in the combustion produces white / sweet smelling exhaust… I suppose the exhaust has a sweet component to it.
I purchase my gasoline from the same name brand station in my family’s other two cars and neither have problems.
Assuming worst case all around, and it is leaking antifreeze into the combustion chamber… could the dealership be using any sort of laced antifreeze to prevent some drastic breakdown within the 3 month warranty period?
Suppose it runs as is for a year, and then breaks down, if it is leaking antifreeze into the combustion chamber… need a new engine?
I saw a reference somewhere that, if the seal is leaking, a compression test could be done to see how bad… can any shop do this? or is this a specialty work?
