Head bolts. Help me understand.

I've read about the head/valve cover bolts breaking on the n52. Was this an issue with early production e90s or is this still a problem with newer cars such as 2010 and newer cars?

why would you be taking your head bolts out?

I can see the valve cover bolts to replace the gasket

So we don't actually know if this has been fixed yet?

I wouldn't be, they used to just break without being touched and the head would come loose and start spilling oil.

Dunno 'bout that. My 2006 N52 has 80,000 miles and she's still holdin' her mud. I doubt that a majority of early N52's popped their head bolts.
