Its up too me to bring it back sharp. Thanks for all the help guys
If you have 107 after aga pipe installed, then it's your rear plate cover.... Very common problem. Once you fix all the leaks and restore factory pressure your car will run much nicer even with 105 tstat!
Damn I don't want to drop the tranny but it seems like the only option. 95c Tstat will save our souls;$


Taken from 5 series forum:
@ 93000 miles both valve covers and both upper timing covers
@ 96000 lower oil pan gasket, water pump, radiator and valley pan (coolant leak)

Now at 103000 and the car is "under construction" again:
- upper oil pan gasket
- oil gasket behind the alternator bracket
- coolant leak behind the transmission (end cover 11147504376) ? very painful project
