White exhaust smoke

Hi Omoyeni,

White smoke is coolant being "burned" in the engine. This is normally caused by a blown head gasket. I would start with checking your coolant level and see if it is low. If it is, top it off because you don't want to run out of coolant because then this could turn from a head gasket to a complete engine replacement.

The next thing you will want to do is test the compression and then do a cylinder leakage test. Assuming you have low compression on one or more cylinders, you will want to do a cylinder leakage test. This will confirm the source of the leak. Once you find that the compression is low, apply pressure to the cylinder and finding where the air is coming out will tell you what needs to be replaced.

If I am correct, you will find low compression and then you will find the air is escaping through the coolant bottle which means the head gasket has failed.

Here are a couple of guides that explain this in a little more detail:

Let me know if you have questions and I will be happy to assist.

Hi, and thank you for using 2carpros. Can you also upload a video of the smoke coming out the exhaust?
