If it was ran low on oil the knock will be bad bearings and that almost 100% always ruins the crank so pulling the whole engine is necessary there to get the crank and cam out and pray it didn't spin a main.
You can pull the oil filter and tear it down (grind the rolled edge off at the top and pull the guts out and spread them out) or pull the pan and see bearing material or even see it in the drain oil you have major issues guaranteed.
Don't you just hate that rapping sound of a rod or bearing in trouble??
