White smoke I might of overfilled it with oil. And another problem is that my car is making a bad tapping noise when coming to a stop and accelerating and this last time I heard a rattling sound. Any ideas?

Good morning,

White smoke is an indication of burning coolant, not oil.

You would have to overfill your oil about 4 quarts before it would smoke but it would be blue, not white.

The common issue is head gaskets that cause this. You need to have a leak down test done to confirm the head gaskets have failed.
