• Q: How to install the cylinder head gasket and related components on 2010 Scion xD?

  A: Installation of the cylinder head gasket starts by placing a new gasket on the cylinder block with the Lot No. stamp oriented upward and thoroughly cleaning the contact surface of oil. The proper mounting orientation is essential to prevent installation damage. Apply engine oil to the threads of the 10 cylinder head bolts before tightening them with plate washers while using a 10 mm bi-hexagon wrench in sequence up to 49 Nm (500 kgf-cm, 36 ft-lbf). Apply paint to mark the front of the cylinder head bolt before tightening it by 90 degrees and another 45 degrees while confirming that the paint hase rotated to 135 degrees relative to the front. Clean the valve lash adjuster assembly while using only engine oil and connect the adjuster to the oil before using the Special Service Tool: 09276-75010 to press down on the check ball and then move the plunger upward and downward to vent air while keeping the check ball fully depressed to let air escape. Install the lash adjusters back to their initial position whenever the plunger becomes hard to operate during bleeding. Staff should apply engine oil to both ends of the lash adjuster tip and valve stem cap before fixing the No. 1 valve rocker arms. After cleaning the No. 1 camshaft bearings, install them correctly and perform a measurement of the distance between the bearing cap edge and the camshaft bearing edge which must remain at 0.7 mm (0.0276 in.) or below. Use the same method to measure the distance between No. 2 camshaft bearings which should be between 1.05 to 1.75 mm (0.042 to 0.068 in.). Apply engine oil to the camshaft journals after cleaning them then install the No. 2 camshaft and main camshaft following each other with correct lubrication. Place the camshaft bearing cap right before tightening its ten bolts to 16 Nm (163 kgf-cm, 12 ft-lbf) using the marked and numbered positions for correct positioning. The technician must apply seal packing continuously to the camshaft housing sub-assembly before removing oil residue and setting it up within 3 minutes to achieve proper tightening of its 17 bolts to a torque of 27 Nm (275 kgf-cm, 20 ft-lbf). Check that cam lobes have their proper orientation before cleaning any escaped seal packing.
