Whys is my car blowing out smoke?

I replaced the engine on the car about 5 month ago and recently is blowing out white smoke? It's a 1997 honda civic ex
It doesn't leak

Head gasket leak. Get fixed as soon as possible or be stranded and risk further damage. You're sure it's not the usual cold weather smoke?

Burning coolant

All cars blow out smoke in the cold mornings? Sure it isn't that? When you turn your heater all the way up

  • Why is my Honda CB250 motorbike spewing out so much smoke? When I run my bike it gives off a lot of smoke when riding and at the lights. As far as I can tell it runs fine, but just smokes a lot. It was so bad tonight that the taxi behind me was pretty much engulfed by smoke, so much so I was worried if he could see the road properly or not. I of tern take it on longish distances (over an hour of riding at about 90ks an hour (56 miles. Could that have damaged it ( I know its not exactly designed for that)
  • Mechanic said he rebuilt the engine, smoke coming out of engine, could it be the grease burning off? The mechanic said he rebuilt the engine to my 1974 Honda CB550 I bought from him. Said he rebuilt the engine and is in perfect running condition. He has many bikes lying around and seems as if he is a hobbyist for bikes. He told me that he basically greased up a lot of parts of the motor and it is burning the grease off. The next oil change I do should remove the excess grease.
  • I replaced my engine in my car and white smoke comes out? I have a1997 honda civic ex and I had to replace the engine and it's blowing out white smoke from the exhaust
  • Smoke coming out from reservoir? Okay so I have a 98 Honda civic 1.6 4 cylinder. Everytime I drive more than 15 minutes I can see smoke coming from right side of hood where my overflow tank is (reservoir) so I open it up and most of the smoke comes from black tube on the cap connected to the overflows tank. I HAVE already replaced radiator cap, radiator hoses (top and bottom) thermostat, fuel filter. I don't know what else I could try? What else could I buy to fix the problem? Buy a new radiator? Any suggestions help
