VIDEO included - e90 n54 coolant issue

Video : Youtube Short


Well. Did a valve cover and gasket change cause a bit of smoking
(Normal)

Car is a n54 with upgraded turbos blah blah blah

Anyways, car was idling after the job ( no load )

Getting up to temp to check for any residual smoke.

Let the car idle for 15 mins to get to temp, and this happened.

Replaced water pump/thermostat/expansion tank and cap

After i add about 1 gallon of coolant it leaks out just a bit and then stops
If i add any more it will leak it all out.

The coolant is falling from water pump and thermostat area.

Which hose or connection do you think it is? Ill find it and tell you if your right eventually lol.

I honestly cant find the leak (so far)

Look at the end tanks in the radiator.
