avenger 2004 white smoke

[brebett]

Hi, my avenger 2004 makes white smoke after warming up a bit. Lots of smoke. what cause that and how to fix. If head gasket do I have to remove the engine.
Thank you

White smoke is coolant burning in the combustion chamber as you already guess it is most likely a head gasket. The motor does not need to be removed to repair it. Pull your spark plugs out and take a look at them, the spark plug that is exceptionally clean (steam cleaned) will be the cylinder with the bad head gasket.

Good luck

If you remove the spark plugs and just turn the key over you will see coolant coming from the plug with the bad head gasket.

If I have to change one is it a good idea to change the gasket on both cylinder

I would do both. Usually have a miss cold when getting coolant in cylinder. I fire up an engine and run for about 20 seconds then shut down. Then feel the exhaust near the head Carefully! The cold one is dead.

Best to do a leak down test on the cyclinders
