You have a head gasket leak. The white smoke is steam from water and antifreeze getting into your cylinders and coming out the exhaust pipe. The bubbles coming up in your radiator is compressed air from the cylinders leaking into the coolant system creating bubbles. The oil is probably either leaking out of the head gasket out of the motor or into the coolant system. You need to get it fixed fast or your vehicle will overheat and damage your engine or water and coolant could flood your cylinders and your engine wont be able to turn over. If you absolutely cannot afford a head gasket repair right now there is a product called Liquid Glass Gasket Sealer. You can flush your radiator and then put in the liquid glass and it may seal. I have to warn you tho the liquid glass thing is time consuming and may not even work, and if it does it is only a temporary fix. If you fix the head gasket now you prevent any further damage to the engine and cylinder heads.

Cylinder compression pressure leaks into the the cooling system past the head-gasket and out the radiator.

I agree with JetDoc, sounds like a blown head gasket I'm afraid. :-(

Sounds like a blown cylinder head gasket to me. Get it checked out. It MAY still be under warranty.

It is most likely your head gasket

your friend may well be correct.

Hello ,

I have a Hyundai click (Getz) car 2006.

Im concerned about a white smoke that comes out from the exhaust and air bubbles coming up into the radiator and sometimes the fluid is pumped out. I also noticed that the oil is less every time i check it so i add some every 8-7 days.

I also think that the oil looks a bit darker in color but im not sure. Forgot to say that i had to change my radiator coz it was leaking it caused my car to overheat since then i noticed those bubles in the new radiator and the white smoke. What do u think the problem is?
