When starting there is a white plume of smoke from tailpipe

Good afternoon,

White smoke is burning coolant.

There are 2 things that could cause it

1. leaking head gasket. You need to have a leak down test done to confirm. This is when you insert shop air into each cylinder and watch for movement of the coolant in the radiator.

2. Intake manifold gasket leaking. It could cross over from a coolant passage to a cylinder.
