It might be oil burning from the valve covers but I'm not to sure how its getting to exhaust.

My brother has this problem but it just smokes in the engine. All he needs is to replace the valve cover gaskets.

I don't know why it's smoking like that. Like I said I replaced the intake manifold gasket and it's holding antifreeze now.

It doesn't take much liquid to make a lot of white smoke. It could be that the radiator pressure is putting antifreeze in a cylinder overnight and then burning off on the first start. Does it continue to smoke white or just on start up?

Then it almost has to be a head gasket or cracked head.
