Coolant Leak Issue, Need Help

O'rei
I thought that could of been some RTV that was pushed out when it was reassembled. But I will take a closer look, thanks!
O'reillys sells a "tank valve" for less than $3 out the door & you can screw it into the 1/8 NPT coolant temp sender port at the top rear of the eng & pump it up to 10 lbs with shop air & see where it leaks. I would "maybe" drain the antifreeze so if it in addition to the external leak that is is leaking internally into the pan that you dont further that. If you go that route you can put some dish soap/water in a squirt bottle & spray the eng potential leak areas & look for bubbling.
