Henry Ford once said, "If you need a machine and don't buy it, you will ultimately find that you have paid for — and don't have it!

OP, this is you in spades! On two different levels.

First,

That engine is not repairable in the car. Pull the engine and fix it!

Second,

Dicking around with all this touchy feely how bad is it hurt discovery stuff is the equivalent of needing the machine and not buying it!

In the end you will not have fixed the engine, still need to fix the engine and now have to begin the process of removal and repair.

Skip all the BS, pull the engine, clean the good parts, trash the bad parts, buy replacement parts and repair your engine!
