Valve, Intake

The procedure to service and repair valve clearance begins with disconnection of the front wheel RH and front fender apron seal RH followed by engine No.1 cover sub-assembly extraction and subsequent removal of spark plug and ventilation hoses and engine wire and cylinder head cover sub-assembly. Perform this operation by disconnecting the engine wire harness clamp and taking out the 8 bolts and 2 nuts and removing cylinder head cover and gasket. Align the timing shaft marks on bearing caps No.1 and No.2 with the marks on the sprocket and camshaft while placing the No.1 cylinder at TDC compress by rotating the crankshaft pulley until it meets timing chain cover mark 0. Test the valve clearance under cold conditions by measuring each valve lifter to camshaft distance with a feeler gauge and note down any measurements beyond the approved range for adjustment shim selection. Continue the clockwise crankshaft rotation for 1 revolution of 360° to establish the No. 4 cylinder at TDC/compression and then measure the clearances once more. When installing the cylinder head cover you must first remove existing FIPG packing then apply the specified Toyota Genuine Adhesive 1344 or Three Bond 1344 or an equivalent product to designated areas of the seal while cleaning away the contact surface oil before installing within 5 minutes of application time and ignoring engine startup for two hours after installation. When installing the cylinder head cover use 8 bolts and 2 nuts which need a torque of 11 Nm (110 kgf-cm, 8 ft. lbs.) for A bolts while B bolts require 14 Nm (143 kgf-cm, 10 ft. lbs.) and applying 11 Nm (110 kgf-cm, 8 ft. lbs.) torque to the nut. Put the spark plug in position before tightening it to 19 Nm (194 kgf-cm, 14 ft. lbs.). Place the front wheel on the right side and check for any oil leaks.

Service the valve clearance by first taking off components at the front wheel RH, front fender apron seal RH, engine No.1 cover sub-assembly, spark plug, ventilation hoses, engine wire, and cylinder head cover sub-assembly. Disconnect the engine wire harness clamp then remove 8 bolts and 2 nuts plus the cylinder head cover and gasket using these components. Turn the crankshaft until the teeth of its pulley fit into TDC position of the timing chain cover at number 0 timing mark while having both camshaft timing gear and sprocket timing marks match bearing caps No. 1 to No. 2 marks. To install the part you should wipe any oil from contact areas before placing seal packing (Part No. 08826-00080 or equivalent) according to provided locations. Replace the cylinder head cover within 5 minutes after packing application. The engine must remain off for more than two hours before starting after you install the new parts. Fasten the cylinder head cover with all 10 bolts while tightening them to 11 Nm at 110 kgf-cm or 8 ft. lbs. Afterward, secure the spark plug using 19 Nm torque at 194 kgf-cm or 14 ft. lbs. Reinstall the ride-hand front wheel lastly check for oil leaks.
