The only other coolant flow across the area you're seeing coolant accumulation is pipe labeled 16268. I highly doubt it would be leaking there though as that is a steel pipe.

The coolant is magically re appearing on the driver side towards the front. I’ve got the intake plenums off now so I can see it pretty well. How is coolant seeping Into this spot with the engine off (and cold) and no pressurization of the cooling system??

I agree with @JRZEE2000TR4LTD it's unlikely 1626862060
PIPE, WATER BY-PASS, NO.1 would just start leaking but it sounds like it is based on your description to me.

somehow? during your work maybe you put pressure on the water by-pass and maybe something was lose enough to cause that to leak?

that connection uses FIP gasket material. it does wear out and it will leak at some point.

we all had a nice chat this very part a while back in this thread. helpful pics included in this thread.
water by-pass o-ring part number?

it could be your lower intake as well but why it would just start leaking a ton like that all of a sudden? but that said anytime you mess with anything mechanical it can upset the balance and cause other issues.

update us when you figure it out. I'm thinking it will be obvious once you find it. I'm curious to know what happened?

thanks
