INTAKE MANIFOLD
Driving and POP coolant all over engine. No over heat
Coolant flows from this nipple/ port.

Does yours go to anything? Does it have a cap on it?

didnt find any hoes it could have gone to. bought a rubber cap and capped it off and everything seems okay. why would this be just an open port for another option of cooling?

I think I may have the same issue. Except my little rubber cap deteriorated and is just barely leaking but causing some decompression issues.

Where did you find the rubber cap?

Thanks
