white smoke from engine on 1998 Ford Explorer

White smoke comes from my engine. If I take off the oil cap smoke comes out, it does not come out of the exhaust. It does not seem to be burning oil. i recently had the radiator and gas pump replaced. If anybody can help that would be awesome, I feel like I have entered a money pit.

That you did. Um smoke out of the oil cap means you have blown piston rings this is called blow-by
