Hey, I recently purchased a 2000 Honda Civic Hatchback and I’ve noticed that sometimes my car will blow white smoke from the exhaust. Is this something that could be a big problem?

 

If it is just condensation smoke, which typically occurs for the first few minutes after cold cranking the engine, and typically ceases once the engine is warmed up... then you have nothing to worry about. If you are also experiencing overheating and/or temperature gauge fluctuations, then the issue may be turning bad.

 

The engine doesn’t overheat, and smoke comes out only occasionally whether I cold crank it or not. Sometimes it goes all day without it happening and sometimes it will come out almost constantly.

 

What brand/type of exhaust do you have on the car ? Sometimes, if the muffler tip is angled up, or there are low spots in the exhaust piping that would accumulate moisture overnight (or collect rain water at the right angle), this water evaporates and appears like white smoke until it is all burned off. If this is your issue, it will NOT smoke when the engine and exhaust system is cold, but once it heats up, the smoking will begin and continue until all water/moisture burns off.
