I know this sounds nuts but...
I see so many post about washed out rings and I wonder---
I had a stroker big block six pack engine on the dyno--custom set new carbs with max mods and build--Fired it up all good ran for about 10 minutes--sounded weird--took about 10-15 minutes of looking everything over until I pulled carb bowls--NO JETS! OK well there is the problem--next we drain the oil--filled a bucket with oil and raw fuel--Ok so rings and who knows what else ruined! So I said why not? Filled with fresh oil--added some jets--swapped plugs--fired it back up--ran normal break in and when dyno day was over it made exactly what it should have to start with--
That was about 2010 and it is still melting tires and making smiles so
If one was going to "wash out" the rings it was that unit
I think that some do for sure but they are tougher than we might think and many that are suspected have not done that at all.

Fix the issue change oil and plugs, set timing and let her rip
