To start with, using any type of “repair in a can” in most cases only cases more greif later on.
No doubt the sealer has caused issue(s).
From what your describing, I would venture a guess that you may have a blockage with in the engine itself.
Hind sight is always 20/20.
After you replaced most of the cooling components ,you should have done a chemical coolant system flush.
My suggestion would be to remove the thermostat, then first flush the system with a good detergent to remove as much of the sealant as possible.
You may need to perform this type of flush several times.
Then use a proper cooling system chemical flush according to the instructions.
