If its grinding while cranking after a severe overheat like that the motor is done for. Likely seized the piston rings and if you cracked the block blew fhe head gasket or cracked the head you'll have coolant in your oil if thats the cae your crank bearings and rod bearings are toast
Sounds like you blew a head gasket or even worse. Get a pressure tester from your local parts store and pressure the system up. Most of the time I've found bad intake gasket and the bypass elbows bad. Parts don't cost much but takes a few hours to fix.

Your fan motor might be fried... and check your coolant, they have a tool which measures its ability to do its job. you might need a radiator flush but start small... THe tool to make sure you anti-Freeze is good is very cheap. By one and test it (it tells you how to test it) then check your fuzes for your Radiator fans in your owners manual. if that is good take your fans off and have them tested. you need to get your fans working again even if you need to by new. And see if your car needs a coolant flush, ( a true flush not a drain and fill

Most likely its just your lifters clapping as they make contact, until the oil starts flowing good through them, then it goes away. My car has been doing that for a long time. Never had any problems. The rods are pushed up by the camshaft, the rods push down rocker arms which then open the valves. The rods are round at the tips and sit in lifters that pump oil through them up to the top of the engine and then out onto the valve springs. If your car has a lot of miles you may consider putting a thicker oil, something like 10w40.
