1st 18, 2nd turn 60 degrees,
3rd turn 60 degrees, 4th turn 60 degrees, 5th turn 10 degrees
Sequence
There's 12 stretched bolts ?
from front of engine count 3 bottom bolt holes in
That's number 1
Above is number 2
To the right is number 3
Below is 4
To the left of number 1 is number 5
Above is 6
And so on working your way out clockwise in that sequence
Remember to do each bolt in that sequence at the first torque setting before angle torqueing each bolt in that sequence
And so on .

Thanks lizzard-t, just to clarify is the the first measurement lbsft or nm?
If memory serves me correct from other vauxhalls its lbsft but no harm in double checking
There's only 10 stretch bolts and 4 small bolts to bolt down around the timing cavity.

Further To Lizzard-t's post above be sure to get brand new bolts there not supposed to be Re-used as the thread is designed to stretch.
