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 in advance

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 N•m (3.0 kgf-m, 22 ftlb)
in alphabetical sequence.
Then tighten all bolts to 69 N•m (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 N•m (3.5 kgfm,
25 ft-lb).
(5) Tighten bolts (C), (D), (E) and (F) to 15 N•m
(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°.
Camshaft Caps
M8 Bolts = 20 N.m (2.0 kgf-m, 14.5 ft-lb)
M6 Bolts = 10 N.m (1.0 kgf-m, 7.2 lb-ft)
Cam Cover = 10 N.m (1.0 kgf-m, 7.2 lb-ft)
Camshaft Timing Wheels = 98 N.m (10 kgf-m, 72.4 ft-lb)
Timing Belt Idlers = 39 N.m (4.0 kgf-m, 28.9 ft-lb)
Timing Belt Tensioner Bracket 25 N.m ( kgf-m, 18 ft-lb)
Timing Belt Tensioner = 39 N.m (4.0 kgf-m, 28.9 ft-lb)
Timing Belt Covers = 5 N.m (0.5 kgf-m, 3.6 ft-lb)
Crankshaft Pulley = 177.m (18kgf-m, 130 ft-lb
Oil Cooler Modine = 55 N.m (5.5 kgf-m, 40 ft-lb)
Water Pump = 12 N.m (1.2 kgf-m, 8.7 ft-lb) – Must be done diagonally and re-checked
Oil Pump = 6.4 N.m (0.65 kgf-m, 4.7 ft-lb)
Inlet Manifold = 25 N.m (2.5 kgf-m, 18 ft-lb)
Exhaust Manifolds = 35 M.m (3.6 kgf-m, 26 ft-lb)
Flywheel = 72 N.m (7.3 kgf-m, 52.8 lb-ft)

I took those tourque settings directly from Subau's own Wk shop manual & I strongly suggest that you do not start making the figures up yourself because you think the factory is wrong.... Everything you are working with is aluminium and there have been plenty of cases of people stripping threads & breaking bolts (especialy the cam cap fixings) because they do not have the tourque figures or have set the tourque wrench incorrectly.
Just ensure that the mating surfaces between the cap and the cyl head are oil free and dry & you will be fine

just been reading through this to torque my head down and there is a slight difference between this and auto data but it equates to the same thing
im still finding it hard to get my head round the fact the 2 central bolts are torqued down slightly more than the outers!
iv got a rough guide to what everything equates to in ft/lb from the nm and degrees of tightening
1. 29nm or i went 21.5ft/lb
2. 69nm or 52ft/lb
3. i went in reverse order slacken by 180 degrees
4. reverse order again slacken by 180 degrees
5. 29nm or 21.5ft/lb
6. 80 - 90 degrees which roughly equates to 51ft/lb
7. a further 40 - 45 degrees i found equates to roughly 65ft/lb
8. the 2 central bolts (a and b or 1 and 2) equates to roughly 70ft/lb
just to add i used all new bolts (although autodata states you do not need to) and thorougly oiled the bolts and washers prior to assembly
let me know if you think what iv done is good bad or indifferent
i know its an old post but gathered it must be called upon quite regularly!
cheers
