I agree
And for what it’s worth, it’s a very common problem on this generation GM small block V8
It’s equally likely to leak into the crankcase, versus an external coolant leak
If it’s a small external coolant leak . . . think seepage . . . you can put off the repair for awhile, provided you monitor the situation and top off coolant as needed
But if it starts going into the crankcase . . . you should plan on fixing it ASAP
