General Technical - Torque settings - I'm after a few torque settings to finish putting my engine together if anyone can help? Camshaft cap bolts (i'm sure someone said 10nm and 20nm but that doesn't seem like anything at all) Cam pulley bolts Crank pulley bolt Do I need to use some thread lock on any of these? Thanks...

Here you go.
Torque settings between Sti & Uk are the same.

Con Rod Big End Caps = 44.6 N.m (4.55kgf-m, 33 ft-lb)

Block Bolts:

12mm Head = 25 N.m (2.5 kgf-m, 18 ft-lb)

14mm Double Hex = 47 N.m (4.8 kgf-m, 34.7 ft-lb)

Sump Baffle Plate = 6.4 N.m (0.65 kgf-m, 4.7 ft-lb)

Oil Pick Up Pipe = 10 N.m (1 kgf-m, 7 ft-lb)

Sump Pan = 5 N.m (0.5 kgf-m, 3.6 ft-lb)

Cylinder Head Bolts:

The text refers to bolts A,B,C etc, they are as follows:

A = Top Middle
B = Bottom Middle
C = Top Left
D = Bottom Right
E = Bottom Left
F = Top Right

When removing Cyl head bolts, they should be undone in the following order. F E D C B A

Refitting Cyl Heads:

(1) Apply a coat of engine oil to washers and
bolt threads.

(2) Tighten all bolts to 29 Nm (3.0 kgf-m, 22 ftlb)
in alphabetical sequence.

Then tighten all bolts to 69 Nm (7.0 kgf-m, 51 ftlb)
in alphabetical sequence.

(3) Back off all bolts by 180 first; back them off
by 180 again.

(4) Tighten bolts (A) and (B) to 34 Nm (3.5 kgfm,
25 ft-lb).

(5) Tighten bolts (C), (D), (E) and (F) to 15 Nm
(1.5 kgf-m, 11 ft-lb).

(6) Tighten all bolts by 80 to 90 in alphabetical sequence.
CAUTION:
Do not tighten bolts more than 90.
(7) Further tighten all bolts by 80 to 90 in alphabetical
sequence.

CAUTION:
Ensure that the total re-tightening angle [in
the two previous steps] do not exceed 180.
