White smoke from exhaust is an indication of an intake/headgasket failure.

Have a compresson test performed to find out.

Also make sure the cooling fans are working, is engine overheating?

No, the engine is not overheating. Is it expensive to have the headgasket changed.

Yes, usually over $1,000 depending on if you change one or both headgaskets.

Was car OK BEFORE the oil change?
