Need help, coolant spilling from overflow
hey guys i Need some help and ideas i have coolant spilling from overflow tank while the engine is running it comes out of this little black o ring hole im not sure if there suppose to be something in there mine has nothing.
the car starts every-time in 3 Mississippi's or less and doesn't smoke no smell, idles fine no acceleration stumble. also i opened the filler-neck to look for bubbles while it was running and i didn't see any so i dont think its the water seals.

That hole is there to allow excess coolant to overflow if you've overfilled. I assume you haven't changed your radiator or topped up the coolant recently?
The issue you have now is more likely than not a failure of a coolant seal. Combustion gasses are making their way past the damaged seal and pressurizing your coolant system causing the overflow.
You're up for a rebuild, sorry.

Are you having to add coolant? Is the buzzer going off? Sounds like the engine may be pushing coolant.
One more reason to delete the ASTs on these cars, makes troubleshooting much easier.

The filler neck does not require a pressure cap, when the overflow is connected to the AST. The filler neck is supposed to just be a flat cap unless the AST is deleted then a pressure cap is installed in that location with the FC filler neck.
So currently the 16 psi cap is doing nothing.
A hydrocarbon test of the coolant system will tell you if the engine has a bad coolant seal.
