Coolant explosion

[asshanson]

Yea I was thinking thermostat housing area, on a 2g it also connects to water pipe with that oring, but now FIAV was mentioned and I'm not sure if I tightened it well. The problem is it only leaks with high rpm, and i just now thought of opening the TB and looking at the same time, guess I don't need a second person now.

Oh, not coming out of tailpipe, running out the back of the car, like on the pavement, car was on a slight uphill.
