    So that large leak happen when I was driving and seized up the water pump. Got a new pump in and took out both elbows to take a look at the O-rings(installed aluminum elbows two years ago) they looked bad, but coolant wasn't coming from them but I went ahead and replaced them. As I'm pouring coolant in I got the engine running and everything is smooth but I see coolant dripping from under the car then it stops. It looks like it could be coming from the back passenger side its hard to tell. Then later with the engine off I went to top it off and coolant is coming out as fast as I'm pouring it in at the same spot. I'm not sure what to do at this point.

    It's kind of hard to guess at where the leak is but the timing cover gasket and a rear freeze plug come to mind of places to leak.

    You'll have to get under it and pinpoint the leak somehow.

    A pretty rare failure but can happen.

    Easy enough fix on the engine like these, rear head can be a struggle to take off because they are heavy.

    Where are you pouring the coolant into the radiator or the overflow bottle?
    An engine is an engine no matter the size.... I think Dr. Seuss said that... or maybe it was Big Weld....
