Coolant Leak extrernal on head gasket ??

Looking for some advise ...

I got a Head leaking externally near the oil cooler ( but not the oil cooler) on a ISM Cummins 400hp - 2002 pre egr

Just got done putting in the Bars Stop leak ... Still leaks

It's more of a bubble type blowing , You can see it coming out

Note ... I have no white smoke and engine still cranks over easy


Thanks

 

I put the stop leak in and followed directions to the - T but was still doing the same level of leak no better - no worse ...

 

I'm not a mech but it looks to be coming out of the gasket where the engine comes together .. I think that's the head gasket but honestly I don't know but it is a gasket of some sort and it's a big gasket ...

My problem area is about a 2-3 inch area where the coolant is spewing from

 

That's what I'm figuring to ..

What's the chances the stop leak cures it ? I've never used it before until today .

 

I had it flushed and cleaned 1 year ago and I always have speed co. Check it at every oil change and change filter regularly

 

Liquid Glass ? Is it better than Bars Stop Leak ? If so where do I find it I got a few auto places around ... Autozone , O'Reielys
