Thanks again for all the help...
I found the proper coolant pressure tester at autozone and plan to pump it up in a few...
If nothing pops out at me, next I'll pull the SC and take a look...
About the SC cooling ports, I said the 2 little yellow o-rings always felt like a gamble when re-mounting the SC...Always felt like they never stayed in place when setting the SC back on the manifold...
Appreciate it!
