If you still have the chance, would you mind looking at the conrod bolt tightening specs in your manual? Unfortunately I couldn`t find the manual for the 2.5 Boxster. Thank you for your time!

For the silicone bead, my manual shows the same path, but mirror image (opposite side).
For the rod bolts on a 2.5L, I expect that 90* is fine, but:
There is a table that shows all the engine bolt torques for the M96/20 2.5L, M96/21 3.2L, and M96/22 2.7L
supplement 42 dated from 2000 says,
"Connecting rod screws with connecting-rod designation...7R
Initial tightening: 20 (15)
Final tightening: 1x90*
Connecting rod screws with connecting-rod designation...7R
Initial tightening: 20 (15)
Final tightening: 1x110*"
(yes, it says the same thing for both sections except for the final tightening. Is the 7R a typo in one of them?)
