that overflow tank is the early warming, after all if it gets worse you can warp the head. Early detection is win ! for sure, and you are smart to catch it early good bird dog'ing you car !!
Bad gasket on the rad cap, might do that if it split that rubber seal there.(in cap)
Running pure water not 50% antifreeze will do this.
but the 3 tests are,
RAD pressure test (gauag)
and
the blue /green die test in the rad (detects exhaust gas on the coolant)
compression test all 4, all read like 180psi . sealevel, wide open throttle test, about. never closed throttle.
signs"??
violent overflow tank effects.
misfiring.
steam out of end of tail pipe on hot engine , warm day.
coolant turns black. or see carbon chunks the coolant.
adding coolant every day, (cold engine , cap of RAD look down neck, oops were is my coolant?
oil in coolant, floating or balls for oil floating.
water in OIL oil , in pan or dip stick looks milky.
water flying of side of head. (radical warping of head) (head block juncture,(gasket seen to leak)
good luck to you !!!

I drove it to work yesterday and it ran fine but when I shut it off it started blowing antifreeze back in the over flow tank. It never got hot, no oil in antifreeze or antifreeze in oil. Not burning any antifreeze that I can see, it doesn't get hot while driving, just when you shut the engine off after driving it , it pukes antifreeze . The temp gauge is running in its normal spot. Could it be anything else besides a blown gasket or cracked head. It has never over heated since I have had it.[/size]
