I changed the timing belt and had to jump it off after dead battery. It finally started, but it sounded rough and white smoke came from tailpipe upon running for about 10 minutes I heard a bubbling sound like boiling water coming from the radiator. So I shut down the engine.

Good evening,

Sounds like you have a failed head gasket from the overheating. Compression leaks in to the cooling system and coolant gets in the combustion chamber and that will produce white smoke and bubbling in the cooling system.

Hi Roy, thank you for responding. The car only overheated for a second or two. I changed the timing belt today and as you know it involves a lot of work. Is there anything in that process that could cause over heating if not put back properly? It will start now but sounds like it is missing or sputtering a little and it overheated when idling for about 10 minutes or so.

Okay, did you do a compression test yet? If the belt failed, you may have a valve damaged from the timing being out.

No, it does not sound like you did anything wrong. Whatever is wrong was wrong before you did the belt.

Also, double-check your timing marks. Retarded valve timing will make it overheat.
