  1. What baffles me is if it were a head gasket how does it maintain pressure for so long? Seems like it would leak down the pressure and maybe push some coolant into a cylinder. There is no white smoke. I have been especially attentive when starting
  2. What baffles me is if it were a head gasket how does it maintain pressure for so long? Seems like it would leak down the pressure and maybe push some coolant into a cylinder. There is no white smoke. I have been especially attentive when starting looking for it. Could there be a head gasket leak so slight that the higher cylinder pressure could get through but not the 15 psi coolant pressure?
  3. I own a 2007 Silverado Classic 1500 5.3L. I have been experiencing an issue for a while where it seems to be burping steam or pressure from the surge tank cap. I have pressure tested it and it held 16 psi for 15 minutes cold, had the surge tank checked for hydrocarbons while running. No white smoke in exhaust and no milky oil. It did get hot a few times this summer but quit doing that when I had replaced thermostat, water pump, the belt, belt tensioner, and radiator. There is residual pressure after it sits for as long as a day, and the upper radiator hose seems to stay somewhat hard. I am at my wits end with this. What other pressure sources are there other than combustion? This screams head gasket to me but other than the pressure no other symptoms exist. The engine has 196k on it and runs perfectly.
