What are the torque specs on a 2002 toyota sienna's spark plugs, air intake manifold, and valve covers? Thank you.

XC-70 (typo) YES.
ALL CARS MADE, FOR SURE LAST 20 YEAR.
HAVE FULL SERVICE MANUAL THAT COVER ALL THAT AND 1ZILLION MORE TOPICS. ALL DO
older cars too, but are weaker before manuals were in digital form.
for sure 2007!
you posted with not country,
and what engines is actually there.
ours USA is. 2.5L L5 engine and 2.4L
has x6---- O-RINGS here.
in, inch/lbs, Divide by 12 to get foot/lbs


a diagram what? a VC?
not sure what that means , and all that is in the SM service manual.
CAN I ASSUME, you need all 10 steps in the manual told to you?>

1. Before servicing the vehicle, refer to the Precautions Section.
2. Remove intake manifold. Refer to Intake Manifold removal and installation.
3. Remove spark plugs from:
   • Cylinders 1 and 5-5-cylinder engine
   • Cylinders 2 and 5-6-cylinder engine
4. Install two camshaft cover press tools 999 5454 into the vacated spark plug holes. Ensure that the bolt in the spark plug well is fully tightened 22 ft. lbs. (30 Nm).
5. Remove Variable Valve Timing (VVT) solenoid.
6. Leave a 0.079-0.118 inch (2-3mm) gap to the camshaft cover when installing the press tools 999 5454
7. Remove all bolts securing the camshaft cover to cylinder head.
8. Use pliers 999 5670 to lift camshaft cover from cylinder head.
   
   • Install pliers at the stop lugs. Start with cylinder 1 and work alternately backwards.
   • Slacken off the wing nuts approximately 2 turns.
9. 
   
   • Repeat the procedure working toward rear of engine.
   • Carefully press out the front and rear camshaft seals.
   • Remove the two press tools 999 5454 from spark plug holes.
   • Remove the camshaft cover.

that?
the install is more complex , including sealants.
and
tighten the bolts in sequence from the center and outwards to 88 inch lbs. (10 Nm).
and

1. Install:
   • Variable valve timing (VVT) solenoid. Use a new gasket. Tighten center bolt to 89 ft. lbs. (120 Nm), center plug to 26 ft. lbs. (35 Nm)
   • Spark plugs and tighten to 22 ft. lbs. (30 Nm)
   • Intake Manifold, refer to Intake Manifold removal and installation

and more, read the manual.

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".

Check this post for the specs.

they are in the factory repair manual.

ok the bolts near the intake manifold put them at 4-5 ft.lb and the bolts near the spark plugs 6-8 ft.lb that should be good

LOOK ON THE FUEL INJECTORS RAIL YOU SHOULD SEE A BLACK CAP THAT LOOK LIKE A TIRE AIR PRESSURE STEM REMOVE THE CAP AND FUEL PRESSURE REGULATOR IS THERE

intake manifold upper and lower 89 in. lbs.

valve cover 89 in. lbs.

Please don't forget to rate. Thank you:

Left side front cylinder head



Cylinder head bolt torque sequence-3.4L engine

Cylinder head by aligning it with the dowel pins

New cylinder head bolts coated with a sealant (such as GM 1052080). Torque the bolts in the proper sequence (1-8) to 37 ft. lbs. (50 Nm). Using a torque angle meter turn the bolts 90 degrees in the proper sequence.

Left side exhaust manifold. Torque the bolts to 12 ft. lbs. (16 Nm).

Spark plugs. Torque the plugs 11 ft. lbs. (15 Nm).

Right side rear cylinder head:



Cylinder head bolt torque sequence-3.4L engine

New cylinder head gasket

Cylinder head on top of the gasket and make certain it is lined up properly with the dowel pins

New cylinder head bolts coated with a sealant (such as GM 1052080). Torque the bolts in the proper sequence (1-8) to 37 ft. lbs. (50 Nm). Using a torque angle meter turn the bolts 90 degrees in the proper sequence.

Right side exhaust manifold. Torque the bolts to 12 ft. lbs. (16 Nm).

Spark plugs. Torque the plugs 11 ft. lbs. (15 Nm).

Spark plug wires

Exhaust crossover pipe. Torque the fastener to 18 ft. lbs. (25 Nm).

Valve rocker arms and pushrods. Torque the fastener to 89 inch lbs. (10 Nm). Using a torque angle meter torque the fastener an additional 30 degrees.

Lower intake manifold. Torque the bolts to 115 inch lbs. (13 Nm).

Upper intake manifold. Torque the bolts to 18 ft. lbs. (25 Nm).

Youre going to have to take the engine cover off and find the coil packs in the center of the valve covers. The rears are located begind the back of the intake manifold, they cant really be seen well. Not an easy task for a beginner. Fronts are really easy, rears are not.
