is that antifreeze? Can't tell stupid iPhone..but if so did you connect the coolant line or you could make sure the clips sealed. Had that happen on the powerstroke. Had a small coolant line that the factory clamp had made an impression but leaked until I put the clamp back on where it had been before.

Are you sure the leak is from the intake and not the heater core hard-line? Look down behind the alternator into the block cavity. Determine how much coolant have sitting in the cavity. Is it over the water pump stem? If so, try to get a visual while the engines running, look for bubbles around the hard-line stem connection. Are you sure it's not leaking from the hard-line at the rear, by the head ? Yea, you want to make sure that you do indeed know where it's leaking. Those areas are common for leaks after a intake gaskets are replaced.

Also, did you use Ford intake gaskets ? Ford has revisions on these gaskets that third party suppliers may not be updated with. Ford Motor thickened these gaskets on the passenger side, because of issues that arose in the past. So Ford is the go-to for intake gaskets.

Yea, see if you can pin-point the leak if possible.

Right, that's the by-pass line. For cold climate systems that come on these trucks.

Check all that mudder.

all of that plus hopefully and I say hopefully because I've done this...you didn't tear or nick the rubber on the intake gasket when you installed

Right, and hopfully no finger prints on the heads or gasket surfaces. Just a little bit of oil can screw that one up. Heads should be lacquer thinnered, gaskets should be hit with mineral spirits, - IF contaminated.

But now I'm gettin picky, - sounds, looks like a gross leak tho, something ain't right lol.
