2. Slide the valve out of its guide about 10 mm (3/8 in.), then measure the guide-to-stem clearance with a dial indicator while rocking the stem in the direction of normal thrust (wobble method). If the measurement exceeds the service limit, recheck it using a new valve. If the measurement is now within the service limit, reassemble using a new valve. If the measurement with a new valve still exceeds the service limit, go to step 3 . Intake Valve Stem-to-Guide Clearance Standard (New): 0.06-0.11 mm (0.002-0.004 in.) Service Limit: 0.16 mm (0.006 in.) Exhaust Valve Stem-to-Guide Clearance Standard (New): 0.11-0.16 mm (0.004-0.006 in.) Service Limit: 0.22 mm (0.009 in.)

1. Inspect valve stem-to-guide clearance (see «VALVE INSPECTION»(ref-290827-S39969190062008072200000) ).
2. As shown below, use a commercially available air-impact valve guide driver (A) modified to fit the diameter of the valve guides. In most cases, the same procedure can be done using the valve guide driver, and a conventional hammer.
3. Select the proper replacement guides, and chill them in the freezer section of a refrigerator for about an hour.
4. Use a hot plate or oven to evenly heat the cylinder head to 300°F (150°C). Monitor the temperature with a cooking thermometer. Do not get the head hotter than 300°F (150°C); excessive heat may loosen the valve seats.
5. Working from the camshaft side, use the driver and an air hammer to drive the guide about 2 mm (0.1 in.) towards the combustion chamber. This will knock off some of the carbon and make removal easier. Hold the air hammer directly inline with the valve guide to prevent damaging the driver. Wear safety goggles or a face shield.
6. Turn the head over, and drive the guide out toward the camshaft side of the head.
7. If a valve guide won't move, drill it out with a 8 mm (5/16 in.) bit, then try again. NOTE: Drill guides only in extreme cases, you could damage the cylinder head if the guide breaks.
8. Take out the new guide(s) from the freezer, one at a time, as you need them.
9. Apply a thin coat of new engine oil to the outside of the new valve guide. Install the guide from the camshaft side of the head, use the valve guide driver to drive the guide into the specified installed height (A) of the guide (B). If you have all 16 guides to do, you may have to reheat the head. Valve Guide Installed Height Intake: 15.2-16.2 mm (0.598-0.638 in.) Exhaust: 15.5-16.5 mm (0.610-0.650 in.)
10. Coat both reamer and valve guide with cutting oil.
11. Rotate the reamer clockwise the full length of the valve guide bore.
12. Continue to rotate the reamer clockwise while removing it from the bore.
13. Thoroughly wash the guide in detergent and water to remove any cutting residue.
14. Check the clearances with a valve (see «VALVE INSPECTION»(ref-290827-S39969190062008072200000) ). Verify that a valve slides in the intake and exhaust valve guides without sticking.
15. Inspect the valve seating. If necessary, renew the valve seat using a valve seat cutter (see «VALVE SEAT RECONDITIONING»(ref-290827-S29127663862008072200000) ).

1. Inspect valve stem-to-guide clearance (see «VALVE INSPECTION»(ref-290827-S39969190062008072200000) ). If the valve guides are worn, replace them (see «VALVE GUIDE REPLACEMENT»(ref-290827-S22349311092008072200000) ) before cutting the valve seats.
2. Renew the valve seats in the cylinder head using a valve seat cutter.
3. Carefully cut a 45° seat, removing only enough material to ensure a smooth and concentric seat.
4. Bevel the upper and lower edges at the angles shown in the illustration. Check the width of the seat and adjust accordingly.
5. Make one more very light pass with the 45° cutter to remove any possible burrs caused by the other cutters. Valve Seat Width Standard (New): 1.25-1.55 mm (0.049-0.061 in.) Service Limit: 2.00 mm (0.079 in.)
6. After resurfacing the seat, inspect for even valve seating. Apply Prussian Blue compound (A) to the valve face. Insert the valve in its original location in the head, then lift it and snap it closed against the seat several times.
7. The actual valve seating surface (B), as shown below by the blue compound, should be centered on the seat. If it is too high (closer to the valve stem), you must make a second cut with the 67.5° cutter to move it down, then one more cut with the 45° cutter to restore seat width. If it is too low (close to the valve edge), you must make a second cut with the 35° cutter (intake side) or the 30° cutter (exhaust side) to move it up, then make one more cut with the 45° cutter to restore seat width. NOTE: The final cut should always be made with the 45° cutter.
8. Insert the intake and exhaust valves in the head, and measure valve stem installed height (A). Intake Valve Stem Installed Height Standard (New): 44.0-44.5 mm (1.73-1.75 in.) Service Limit: 44.7 mm (1.76 in.) Exhaust Valve Stem Installed Height Standard (New): 44.1-44.6 mm (1.74-1.76 in.) Service Limit: 44.8 mm (1.76 in.)
9. If valve stem installed height is beyond the service limit, replace the valve and recheck. If it is still beyond the service limit, replace the cylinder head, the valve seat in the head is too deep.

10. Tighten the cylinder head bolts in sequence to 40 N.m (4.0 kgf.m, 29 lbf.ft). Use a beam-type torque wrench. When using a preset-type torque wrench, be sure to torque slowly and do not over torque. If a bolt makes any noise while you are torquing it, loosen the bolt and torque it from the first step.
11. After torquing, torque all cylinder head bolts in two steps (90° per step) using the sequence shown in step 10 above. If you are using a new cylinder head bolt, torque the bolt an extra 90°. NOTE: Remove the cylinder head bolt if you torqued it beyond the specified angle, and go back to step 6 of the procedure. Do not loosen it back to the specified angle.
12. Install the rocker arm assembly (see «ROCKER ARM ASSEMBLY INSTALLATION»(ref-290827-S21095392312008072200000) ).
13. Install the cam chain (see «CAM CHAIN INSTALLATION»(ref-290827-S28985890682008072200000) ).
14. Tighten the three bolts (A) securing the evaporative emission (EVAP) canister purge valve bracket, and torque the two bolts (B) securing the harness brackets.
15. Connect the following engine wire harness connectors, and install the wire harness clamps from the cylinder head: Four injector connectors Engine coolant temperature (ECT) sensor 1 connector Camshaft position (CMP) sensor A connector (Intake side) Camshaft position (CMP) sensor B connector (Exhaust side) Rocker arm oil control solenoid (VTEC solenoid valve) connector Rocker arm oil pressure switch (VTEC oil pressure switch) connector
16. Connect the upper radiator hose (A), the heater hoses (B), and the water bypass hose (C).
17. Connect the positive crankcase ventilation (PCV) hose (A) and ground cable (B).
18. Install the exhaust manifold (see «EXHAUST MANIFOLD REMOVAL AND INSTALLATION»(ref-290821-S39529152502008072200000) ).
19. Install the intake manifold (see «INSTALLATION»(ref-290821-S27171017002008072200000) ).
20. Connect the EVAP canister hose (A) and brake booster vacuum hose (B).
21. Tighten the bolt securing the connecting pipe support bracket to the engine block.
22. Connect the fuel feed hose (A) (see «FUEL LINE/QUICK-CONNECT FITTING INSTALLATION»(ref-290822-S29701361102008072200000) ), then install the quick-connect fitting cover (B).
23. Install the intake air duct (A), then connect the mass airflow (MAF) sensor/intake air temperature (IAT) sensor connector (B), and connect the vacuum hose (C) and breather pipe (D).
24. Install the drive belt (see «DRIVE BELT REPLACEMENT»(ref-290825-S35994715752008072200000) ).
25. After installation, check that all tubes, hoses, and connectors are installed correctly.
26. Inspect for fuel leaks. Turn the ignition switch to ON (II) (do not operate the starter) so the fuel pump runs for about 2 seconds and pressurizes the fuel line. Repeat this operation three times, then check for fuel leakage at any point in the fuel line.
27. Refill the radiator with engine coolant, and bleed air from the cooling system with the heater valve open (see «COOLANT CHECK»(ref-290817-S27864475492008072200000) ).
28. Do the engine control module (ECM)/powertrain control module (PCM) idle learn procedure (see «ECM/PCM IDLE LEARN PROCEDURE»(ref-290807-S02808252682008072200000) ).
29. Do the crankshaft position (CKP) pattern clear/CKP pattern learn procedure (see «CRANK (CKP) PATTERN CLEAR/CRANK (CKP) PATTERN LEARN»(ref-290833-S05169572102008072200000) ).
30. Inspect the idle speed (see «IDLE SPEED INSPECTION»(ref-290807-S38509989942008072200000) ).
31. Inspect the ignition timing (see «IGNITION TIMING INSPECTION»(ref-290826-S15240868122008072200000) ).
