Order to take head bolts/studs off?
Hey guys, im sorry I searched and nothing. I forgot what orderin which you take the head studs/bolts off so not to damage the head. This is for a B18A/B18B.
I had a diagram awhile ago but I lost and forgot the order.
TIA,
Eric

Alright my freind helped me out, In case anyone ever needs to know, it goes (from timing belt side):
1: Closest to timing belt intake side
2. Furthest from timing belt exhaust side
3. Furthest from timing belt int. side
4. Closest to timing belt exh side.
Then repeat the pattern.

Then repeat the pattern.
Will you make something up for me please?

Removal would be the opposite of the installation.....here's the post I made. Look at my post.

Cylinder Head Bolt Torque Sequence
Lay the head horizontally, so the intake is away from you and the exhaust ports are facing you. Going across, from the top left to the top left of the intake side the order is 9, 5, 1, 3, 7. Going across from the bottom left to the bottom right on the exhaust side, the order is 8, 4, 2, 6, 10

INTAKE
===========
| 9 5 1 3 7 |
| 8 4 2 6 10 |
===========
EXHAUST
They are 11x1.5mm bolts that should be torqued down 85 Nm or 63ft-lbs. Note that they should be tightened in a two step sequence. First use the above order and torque them to 22ft-lbs, then again in that order to 63ft-lbs.
Intake manifold should be bolted on in a criss cross pattern beginning with the inner nuts. Those should be torqued to 17ft-lbs. The IM bracket if you still have it should be torqued 17ft-lbs as well.
