How much sludge can an SD220 handle?
Obviously the 220 can handle lots of sludge. I would be concerned about the sludge blocking the oilpump pick-up. I would advise cleaning the oil pan and not disturbing anything else until the engine gets rebuilt.
If this was my engine I would be installing a 185* minimum thermostat. A first oil-change at 500-1000 miles is a good idea.
It is very unlikely this engine will ever see that level of sludging again. Modern fuel does not have ethyl lead. Ethyl lead was the source of the sludging and it was an inexpensive way to raise the octane in fuel. Thousands of persons died from being poisoned by the ethyl lead. It used to be said, "There are not old mechanics." The ethyl lead was the reason. Wear nitryl gloves to protect your hands. If you get enough lead into your system, your pecker will stop working first, then other organs will follow.
When it comes to the filter, totally plugged will not restrict the engine oiling system. The filter is a by-pass. Google this for more information. By-pass is not a bad thing, just a little different than full-flow. Some more modern and very expensive engines have both bypass and full flow. Your engine is in good company.
