Anybody knows exact sizes and locations of valve cover bolts on N52?
Car F10 2011 with N52 engine (plastic valve cover)
. cannot figure out where 11127558449 and 11127558450 go (https://www.realoem.com/bmw/enUS/sho...diagId=11_3737)
are these bolts in the 2 corners of valve cover gasket?
I counted 19 bolts in total which are located on edges of valve cover:
-> 2 removable torx bolts (11127558454)
-> 15 "stay in valve cover" torx bolts ( 11127558448)
-> 1 "stay in valve cover" torx bolt ??? (11127558449) if so which corner?
-> 1 "stay in valve cover" torx bolt ??? (11127558450 ) if so which corner?

I have a torx bolt head partially stripped in the corner of valve cover (passenger side towards the car's saloon) and wanted to order one.
