Kia Soul: Valve Clearance Adjustment

Kia Soul: Valve Clearance Adjustment

  
Inspect and adjust the valve clearance when the engine is cold (Engine coolant temperature : 20°C) and cylinder head is installed on the cylinder block.
Remove the cylinder head cover.
Set No.1 cylinder to TDC/compression.
Turn the crankshaft pulley and align its groove with the timing mark of the timing chain cover.

Check that the marks of the intake and exhaust CVVT sprockets are in straight line on the cylinder head surface as shown in the illustration. If not, turn the crankshaft one revolution (360°).

Inspect the valve clearance.
Check only the intake valves of the 1st and 2nd cylinders and exhaust valves of the 1st and 3rd cylinders for their clearance.
A.
Using a thickness gauge, measure the clearance between the tappet and the base circle of camshaft.

B.
Record the out-of-specification valve clearance measurements. They will be used later to determine the required tappet for adjusting.
Valve clearance specification (Engine coolant temperature : 20°C [68°F])
Limit
Intake : 0.17 0.23mm (0.0067 0.0091in.)
Exhaust : 0.22 0.28mm (0.0087 0.0110in.)
Turn the crankshaft pulley one revolution (clockwise 360°) and align its groove with timing mark of the timing chain cover.
Check the intake valves of the 3rd and 4th cylinders and exhaust valves of the 2nd and 4th cylinders for their clearance.

Adjust the intake and exhaust valve clearance.
Set the No.1 cylinder to the TDC/compression position.
Remove the timing chain. (Refer to Timing system)
  
Put paint marks on the timing chain links (2 places) that meet with the timing marks of the intake and exhaust CVVT sprockets.

Remove the camshaft bearing caps (A) with the order below.

Remove the intake camshaft assembly.
Remove the exhaust camshaft assembly.
Measure the thickness of the removed tappet using a micrometer.

Calculate the thickness of a new tappet so that the valve clearance comes within the specificified value.
Valve clearance (Engine coolant temperature : 20°C)
T : Thickness of removed tappet
A : Measured valve clearance
N : Thickness of new tappet
Intake : N = T + [A - 0.20mm(0.0079in.)]
Exhaust : N = T + [A - 0.25mm (0.0098in.)]
Select a new tappet with a thickness as close as possible to the caculated value.
  
Shims are available in 41 size increments of 0.015mm (0.0006in.) from 3.00mm (0.118in.) to 3.690mm (0.1417in.)
Place a new tappet on the cylinder head.
Install the exhaust camshaft assembly.
Install the intake camshaft assembly.
Install the camshaft bearing caps with the order below.
Tightening torque :
1st step
M6 bolt :
5.9 N.m (0.6 kgf.m, 4.3 lb-ft)
M8 bolt :
9.8 N.m (1.0 kgf.m, 7.2 lb-ft)
2nd step
M6 bolts :
11.8 13.7N.m (1.2 1.4kgf.m, 8.7 10.1lb-ft)
M8 bolts :
18.6 22.6N.m (1.9 2.3kgf.m, 13.7 16.6lb-ft)

Install the timing chain. (Refer to Timing system)
Turn the crankshaft two turns in the operating direction(clockwise) and check that the marks of the intake and exhaust CVVT sprockets are in straight line on the cylinder head surface.

Recheck the valve clearance.
