Hi all, first post....

I researched all I could about the leak I have on my truck and still would like more info.

Some possible areas that I could point the finger would be the; heater core, thermostat housing, hoses, manifold etc....

The coolant is visible up top and puddles up around an injector and some other areas. It then shows up down below dripping quickly by the tranny...

I just got back from a 900mi round trip to Vegas with my truck and not once did it 'feel' I had an issue. I was towing a car down that I had sold, Gauges all read well to and from Vegas. I did notice though that when I stopped to fill up in St. George Utah that we heard what sounded like 'ice chunks' breaking off and falling behind the glovebox...??? That's about it.

Truck info; 93,500mi-5.4L, 4wd

I recorded some video, a bit choppy looking from the top and bottom--I can make another if this one sucks

I'm thinking the intake is leaking at the aluminum crossover.
