Ok, never had this happen before. I first thought the intake gasket was leaking.... But no! It is leaking right where casting circle is (passenger side)

I wish that could good picture the leak, but my intake is on the car. Used a spare to show location. I found my telescoping mirror and now see, what looks like stress fracture from the circle to front of intake. Is this common? Dont, think I have seen a post about it.

I have been reading through all kinds of posts on here and have found zero intake failures.

What's leaking?  Coolant?  Vacuum?  Exhaust?

Upon closer inspection is that the bottom of your intake?  If so there's no way that's the source of the what appears to be coolant residue.

I haven't experienced or heard of an intake manifold cracking.  Doesn't mean it can't happen, but I'd guess it's rare.

I appologize for not stating it was a coolant leak. Yeah, it is weird...

There is a 1/4" bypass hose that runs from your intake to thermostat housing.  Check that for leaks.  Sometimes, the hose will only leak when the coolant is up to boiling temp ... then steam will spray out of the damaged part of the hose.     And 1/4" is the ID.

Yeah, check that hose, and the barbs it hooks to.

As you can see, hopefully, the casting is not to thin, not saying it couldn't happen, if you can put a sharp piece of steal through it then yes, that's were it's coming from.

Well.. I'm dumb. I hate to admit it, but I over looked something. The upper rad hose clamp was not tight and coolant was streaming along the thermostat and under the intake. Always tell others the think small and I failed to follow my own advise. ????
