There is white smoke coming out of the exhaust

Hello,

White smoke out of the tail pipe is a sign of a blown head gasket.
Check your oil to see if it is milky color which will indicate coolant in the oil.

If the initial head gasket was replaced due to overheating is could be that there is a crack in
the head and that's where it is leaking coolant into the oil.

It can also be due to not having the head bolts torqued properly in the correct sequence.

If the coolant is mixing with oil you will have to replace the head gasket again. But you need to make sure that the head is not cracked. Usually machine shops can test for cracked head.
