i have my black top in my s14, its running 15psi well i went and did a radiator coke water test i see small air bubbles in diagnostic.

very small bubbles in idle and one slight good size bubble when i do rev it and nothing constant. my dash gauge shows just over half almost to say 3/4 or less to hit hot really hot.
what i have notice is that when i gun it after i do my radiator cap is showing sign of overflow, but in regular driving it doesnt over heat...


possible blown head gasket???

What temp sensor are you using? You need to use the one intended for the chassis, not the motor.

Remove the thermostat and bleed again. See if it over heats. I find it better not to use one if you have a bigger turbo/Running over stock boost. :)

Do this above b4 assuming the head gasket. You aren't going to see any water/coolant leaking. Engine will evaporate it most of the time. ;)
