Quite a bit of white smoke from exhaust after head gasket replacement
Vehicle: 2014 Chevy Suburban LS 1500
Hello guys,
I was recently in a car accident where a tree basically fell on my hood, destroying my intake manifold and there was plastic sucked into the cylinders, so I decided to take the heads off to get them and in the process replace the head gasket. I used ACDelco MLS head gasket with fel-pro TTY bolts, then got the heads resurfaced. Plus new OEM intake manifold. I followed the sequence of 22 ft lbs + 90 deg + 70 deg in the right bolt order.
I still have to replace two vacuum that broke plus a handful of coolant leaks around the car. I was still waiting on new air duct so I just pulled the old MAF sensor and connected it, basically just left it dangling in the engine bay.
After putting everything together, I tried running the engine. It would not run without giving it some gas, then it would idle fine. I noticed a lot of white smoke coming out of exhaust plus the obvious coolant leaks near the radiator, but the white smoke makes me afraid that I botched the head gasket job.
How can I make sure if my head gasket is leaky? Should I be concerned? How would you guys narrow down which bank of a V8 has the leak?
Is the rough initial idle from the bad vacuum lines?
