BMW's don't like getting hot due to the alum. heads. If you overheated it multiple times and now it won't start, you have a major issue. Did you bleed the cooling system/remove trapped air after you swapped out the parts? Might be a head gasket or time for a new engine. Any connections wet? Best to have the pro's diagnosis it for you at this point.

Probably a head gasket issue, you can do a leak down and or a cylinder compression test to make sure.

Yeah, you can't overheat these cars repeatedly. Very easy to warp the heads.

It sound to me another engine block damage by excessive heat. I can assure you have loose head bolts due to damage threads
