Torque specification for valve cover bolts on 403 engine

The KIA shop manual (both my hard copy and kiatech) show the locations of the bolts on the "Cylinder Head Cover" --aka valve cover-- and they provide the torque at 35-52 lb-in (4-6Nm), but they don't specify a tightening order.

Normally crisscross middle to outside edges, hand tight, half torque and full torque. Better to do the job right, do it once, replace the gasket.

The torque specification for the cylinder valve cover stud/bolt on a 2007 Honda Accord 2.4L VTi is 7.2-8.1 lb-ft (10-11 Nm).
As for replacing the broken stud, it depends on how the broken stud is located and the extent of the damage. If the broken stud is easy to access, it may be a simple matter of unscrewing the old one and putting a new one in with the correct torque specification. However, if the broken stud is difficult to access or if it has caused damage to the threads, it may require a more complex repair. In some cases, it may be necessary to drill out the old stud and tap new threads or to use a helicoil insert to repair the damaged threads.
It's important to note that over-tightening the valve cover bolts/studs can lead to damage or deformation of the valve cover or gasket, and under-tightening can lead to oil leaks. So, it's crucial to torque the bolts/studs to the specified torque value.

I can give you the numbers for a 2009 3.5, dont have 07 service manuals. Probably the same.

RH & LH valve cover is 89 in-lb.
For bolts 17, 18. 19 & 20 the spec is 27 in-lb
(Stage 1) Bolts 1-22 are 89 in-lb, bolts 23, 24 & 25 are 133 in-lb

(Stage 2) bolts 1-22 are now tightened to 17 ft-lb, bolts 23, 24 & 25 are now 55 ft-lb.

Note however that there is a VERY specific process for this repair involving the use of Motorcraft High Performance RTV Silicone to seal the covers. According to the service manual, failure to get this right "may cause oil to foam and result in serious engine damage."

The processes, especially for the front cover, water pump, timing chain and guides are very specific and require specific actions to br done at specific points. IF YOU DO NOT FOLLOW A SERVICE MANUAL you run the real risk of causing serious engine damage.

Go on your computer in your browser and type in '1990 Honda Accord 2.2 4 cylinder head bolts torque specifications'. You will get back the engine bolt layout with the bolts numbered with the torque specs. You tighten the bolts according to the numbers of the bolts in the order starting with number 1 and working to the highest number.

20. INSTALL CYLINDER HEAD COVER SUB-ASSY
(a) Apply seal packing to the cylinder head as shown in the
illustration.
Seal packing: Part No. 08826-00080 or equivalent
NOTICE:

Remove any oil from the contact surface.

Install the cylinder head cover within 3 minutes after
applying seal packing.

Do not start the engine within 2 hours after installing.
(b) Install the cylinder head cover with the 9 bolts. Tighten the
bolt uniformly in several steps.
Torque: 8.0 Nm (80 kgf cm, 71 in.lbf)
(c) Install the engine wire harness with the 3 nuts.
Torque: 8.4 Nm (85 kgf cm, 74 in.lbf)
21. INSTALL CYLINDER HEAD COVER SUB-ASSY LH
(a) Apply seal packing to the cylinder head as shown in the
illustration.
Seal packing: Part No. 08826-00080 or equivalent
NOTICE:

Remove any oil from the contact surface.

Install the cylinder head cover within 3 minutes after
applying seal packing.

Do not start the engine within 2 hours after installing.
(b) Install the cylinder head cover with the 9 bolts. Tighten the
bolt uniformly in several steps.
Torque: 8.0 Nm (80 kgf cm, 71 in.lbf)
(c) Using an E6 torx) socket wrench, install the engine wire
harness protector with the 2 bolts.
Torque: 8.4 Nm (85 kgf cm, 74 in.lbf)

This is year/make/model specific to the 2nd Gen Sienna. Taken from the 05 Toyota Sienna repair manual. Hope this answers your torque specs for the valve covers which uses 10 mm bolts. If in doubt, as Scotty Kilmer asserts, do a "German tight".

Fig. : Cylinder head torque sequence, 260, 307, 350 403 Oldsmobile built engines




On the V8, tighten the bolts, in the sequence illustrated, to 100 ft. lbs. When all bolts have been tightened to this figure, begin the tightening sequence again, and torque all bolts to 130 ft. lbs.

On V6's, tighten all head bolts in sequence to the following torques:
* All except bolts 5, 6, 11, 12, 13 and 14 - 100 ft. lbs.(19-135.5 Nm)
* Bolts 5, 6, 11, 12, 13, and 14 - 41 ft. lbs. (19-55.5 Nm)
* All bolts except 5, 6, 11, 12, 13, and 14 - 142 ft. lbs. (19-192.5 Nm)
* Bolts 5, 6, 11, 12, 13, and 14 - 59 ft. lbs. (19-80 Nm)
