2006 Altima 2.5 I believe with blown head gasket. All four pistons have coolant sitting on top. Once this happens, I blow it out then it will start and run good with no codes, however when I turn it off after about 1/2 hour crack no start???
You have a blown head gasket. What's happening is you are essentially hydrological engine when you turn it off. You then have to wait for it to release pressure before it all allowed self to start again.
