Ok so a few weeks ago I had the ac fixed and when I ran er she overheated w ac on, bad tensioner. So anyway I made it home but I had a puff of white smoke out the tailpipe and sum steam from the back of engine around lower intake area. There didn't appear to be any h2o in the oil. The intake bolts were a little loose if that has anything to do w anything. Is there any way to tell if its intake or head gasket before its torn down? Oh and the car didnt overheat w ac off even after puff of smoke out the tail. That was a 30 mi ride home.
