I just finished getting my car back together with a freshly rebuilt motor. After taking it on its second ride for the break in period, I got on it to load the motor a bit and suddenly saw a huge white puff of smoke behind the car. I popped the hood when I got home and coolant had spewed all over the passenger side header. I checked the oil dipstick and it looks fine along with the coolant itself. I started it back up with the cap off the reservoir and no bubbles came up. I also don't hear any signs up a blown head gasket.
What just happened with my new motor?? I don't understand and I'm extremely discouraged right now![Frown :( :(](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
