2. Set No. 1 cylinder to TDC/compression. Turn the crankshaft pulley clockwise and align its groove with the timing mark "T" of the lower timing chain cover. Check that the mark of the camshaft timing sprockets are in straight line on the cylinder head surface as shown in the illustration. If not, turn the crankshaft clockwise one revolution (360°). NOTE: Do not rotate engine counterclockwise.
3. Inspect the valve clearance. With No. 1 cylinder at TDC inspect clearances only on the valves shown in diagram below. Measurement method. Using a thickness gauge, measure the clearance between the tappet and the base circle of camshaft. Record the out-of-specification valve clearance measurements.

Description

Continuous Variable Valve Timing (CVVT) system advances or retards the valve timing of the intake and exhaust valve in accordance with the ECM control signal which is calculated by the engine speed and load.

By controlling CVVT, the valve over-lap or under-lap occurs, which makes better fuel economy and reduces exhaust gases (NOx, HC). CVVT improves engine performance through reduction of pump loss, internal EGR effect, improvement of combustion stability, improvement of volumetric efficiency, and increase of expansion work.

This system consist of

1. the CVVT Oil Control Valve (OCV) which supplies the engine oil to the cam phaser or runs out the engine oil from the cam phaser in accordance with the ECM PWM (Pulse With Modulation) control signal
2. the CVVT Oil Temperature Sensor (OTS) which measures the engine oil temperature
3. and the Cam Phaser which varies the cam phase by using the hydraulic force of the engine oil.

The engine oil released out of the CVVT oil control valve varies the cam phase in the direction (Intake Advance/Exhaust Retard) or opposite direction (Intake Retard/Exhaust Advance) of the engine rotation by rotating the rotor connected with the camshaft inside the cam phaser.

Scheme 131

Operation Principle

The CVVT has the mechanism rotating the rotor vane with hydraulic force generated by the engine oil supplied to the advance or retard chamber in accordance with the CVVT oil control valve control.

Camshaft end play [Standard value]: 0.02 ~ 0.18mm (0.0008 ~ 0.0071in.) If the end play is greater than maximum, replace the camshaft. If necessary, replace cylinder head. Remove the camshafts.

Reassembly

Note. Thoroughly clean all parts to be assembled. Before installing the parts, apply fresh engine oil to all sliding and rotating surfaces. Replace oil seals with new ones.

1. Install the valves. Using the SST (09222-2W100), push in a new oil seal. NOTE: Do not reuse old valve stem seals. Incorrect installation of the seal could result in oil leakage past the valve guides. Install the valve, valve spring and spring retainer. NOTE: Place valve springs so that the side coated with enamel faces toward the valve spring retainer and then install the retainer. Using the SST (09222 - 3K000, 09222-3K100), compress the spring and install the retainer locks. After installing the valves, ensure that the retainer locks are correctly in place before releasing the valve spring compressor. Lightly tap the end of each valve stem two or three times with a soft hammer or the wooden handle of a hammer to ensure proper seating of the valve and retainer lock.
2. Install the MLAs. Check that the MLA rotates smoothly by hand. NOTE: MLA can be reinstalled in its original position. However, the valve lash clearances must be rechecked and adjusted accordingly before the cylinder head is installed onto the cylinder block. Refer to General information in EM section for Valve Clearance checking and adjustment procedure.
3. Install the LH/RH intake camshaft CVVT OCV (A). Tightening torque 9.8 ~ 11.8Nm (1.0 ~ 1.2kgf.m, 7.2 ~ 8.7lb-ft) NOTE: Install OCV with gray colored connector into RH bank. Install OCV with black colored connector into LH bank. CAUTION: Do not reuse the OCV when dropped. Keep the OCV clean. Do not hold the OCV sleeve during servicing. When the OCV is installed on the engine, do not move the engine while holding the OCV yoke.

Installation

Note. Thoroughly clean all parts to be assembled. Always use a new head and manifold gasket. The cylinder head gasket is a metal gasket. Take care not to bend it. Rotate the crankshaft, set the No. 1 piston at TDC.

1. Install the cylinder RH head. The sealant locations on cylinder head and cylinder block must be free of engine oil and ETC. Apply TB 1217H (Hyundai Gray RTV) sealant on cylinder block top face before assembling cylinder head gaskets. The part must be assembled within 5 minutes after sealant was applied. NOTE: Refer to below illustration to apply the sealant. Bead width: 2.0~3.0 mm (0.078 ~ 0.118 in.) Sealant locations: 1.0~1.5mm (0.039 ~ 0.059 in.) from block surface Recommended sealant : TB 1217H (Hyundai Gray RTV) Liquid sealant Apply TB 1217H (Hyundai Gray RTV) sealant on cylinder head gaskets after assembling cylinder head gaskets on cylinder block. The part must be assembled within 5 minutes after sealant was applied. NOTE: Be careful of the installation direction. Install the RH cylinder head. NOTE: Remove the extruded sealant after assembling cylinder heads.
2. Install the RH cylinder head bolts. Do not apply engine oil on the threads and under the heads of the cylinder head bolts. Using SST (09221-4A000), install and tighten the cylinder head bolts and plate washers, in several passes, in the sequence shown.in the illustration. CAUTION: Always use a new cylinder head bolts. Tightening torque Head bolt: 37.3~41.2N.m (3.8~4.2kgf.m, 27.5~30.4lb-ft) + (118~122°) + (88~92°) Bolt (A): 18.6 ~ 23.5Nm (1.9 ~ 2.4kgf.m, 13.7 ~ 17.4lb-ft)
3. Install the other parts reverse order of removal. NOTE: Refill engine oil. Clean the battery posts and cable terminals with sandpaper. Assemble and then apply grease to prevent corrosion. Inspect for fuel leakage. After assembling the fuel line, turn on the ignition switch (do not operate the starter) so that the fuel pump runs for approximately two seconds and fuel line pressurizes. Repeat this operation two or three times, then check for fuel leakage at any point in the fuel lines. Refill radiator and reservoir tank with engine coolant. Bleed air from the cooling system. Start engine and let it run until it warms up. (Until the radiator fan operates 3 or 4 times.) Turn Off the engine and let it cool down. Check the level in the radiator, add coolant if needed. This will allow trapped air to be removed from the cooling system. Put radiator cap on tightly, then run the engine again and check for leaks.
