superpoo93 Posted March 2, 2016 Share Posted March 2, 2016 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) Quote Link to comment Share on other sites More sharing options...
superpoo93 Posted March 2, 2016 Author Share Posted March 2, 2016 (edited) 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.

firehawk618 Posted March 2, 2016 Share Posted March 2, 2016 I have been reading through all kinds of posts on here and have found zero intake failures.What's leaking? Coolant? Vacuum? Exhaust? Quote Link to comment Share on other sites More sharing options...
firehawk618 Posted March 2, 2016 Share Posted March 2, 2016 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. Quote Link to comment Share on other sites More sharing options...
DaveT Posted March 2, 2016 Share Posted March 2, 2016 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. Quote Link to comment Share on other sites More sharing options...

rdweninger Posted March 2, 2016 Share Posted March 2, 2016 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.

DaveT Posted March 2, 2016 Share Posted March 2, 2016 Yeah, check that hose, and the barbs it hooks to. Quote Link to comment Share on other sites More sharing options...
machineit Posted March 3, 2016 Share Posted March 3, 2016 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. Quote Link to comment Share on other sites More sharing options...
superpoo93 Posted March 6, 2016 Author Share Posted March 6, 2016 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. ????
