NOTE: Samurai & Sidekick 1) Remove rocker cover. Rotate crankshaft until zero degree (TDC) timing mark of timing belt cover is in line with timing mark on crankshaft pulley. 2) Cylinder No. 1 should be at TDC on compression stroke. Remove distributor cap, and ensure rotor is pointed upward at distributor hold-down bolt and to No. 1 terminal of distributor cap. If not as described, rotate crankshaft 360 degrees. 3) Measure valve clearance between adjustment screw and valve stem using thickness gauge. Check intake valve clearance of cylinders No. 1 and 2 and exhaust valve clearance of cylinders No. 1 and 3. 4) Turn crankshaft one complete revolution (360 degrees).

NOTE: Hydraulic valve lifters are used; no valve adjustment is required. When valve and/or valve seat is machined, valve clearance is reduced and may cause improper valve operation. Different length push rods are available for correcting clearance. Valve lifter must be collapsed to check valve clearance. 1. With valve cover removed, position piston No. 1 at TDC of compression stroke. Completely collapse cylinder No. 1 intake valve lifter and hold valve lifter collapsed. Using feeler gauge, measure clearance between rocker arm and valve stem. 2. Clearance should be within specification. Refer to COLLAPSED VALVE LIFTER CLEARANCE table. Replace push rod, if necessary, to obtain correct clearance. 3. Position crankshaft as specified. See, in this article, VALVE CLEARANCE CHECKING SEQUENCE table, and check appropriate valves. Replace push rods if clearance is not within specification. 4. If push rod(s) is replaced, ensure corresponding cylinder piston is below TDC. It will be necessary to loosen or remove rocker arm to replace push rod. CAUTION: DO NOT operate or crank engine after installing push rod until valve lifter has leaked down to normal operating position. COLLAPSED VALVE LIFTER CLEARANCE

Valves should be adjusted only when the cylinder head temperature is less than 100° (38° . F C) After adjusting, retorque the crankshaft pulley bolt to 245 N.m (25.0 kgf.m, 181 lbf.ft) . 1. Remove the cylinder head cover. 2. Set No.1 piston at TDC . “UP” mark on the camshaft pulley should be at top, and TDC grooves on the camshaft pulley should align with cylinder head surface. 3. Adjust valves on No.1 cylinder. Intake: 0.26 mm ±0.02 mm (0.010 in) ± (0.0008 in) Exhaust: 0.30 mm ±0.02 mm (0.012 in) ±(0.0008 in) 4. Loosen the locknut, and turn the adjusting screw until the feeler gauge slides back and forth with a slight amount of drag. 5. Tighten the locknut and check clearance again. Repeat adjustment if necessary. 6. Rotate crankshaft 180° counterclockwise (Camshaft pulley turns 90° . The ) “UP” mark should be on the exhaust side. Adjust valves on No.3 cylinder. 7. Rotate crankshaft 180° counterclockwise to bring No.4 piston to TDC . Both TDC grooves are once again visible. Adjust valves on No.4 cylinder.

REMOVAL NOTE: The oil pump and valve body are removed as an assembly. 1. Disconnect battery ground cable, then remove battery, battery tray, and remote air cleaner. 2. Position supply hoses, vacuum hoses, and wiring away from pump and valve body cover. 3. Remove shift lever. 4. On models equipped with Anti-lock Brake System (ABS) , remove splash shield cover, then disconnect brake reservoir hose and cap to prevent contamination. 5. On all models, remove EGR bracket attaching bolts, then install lifting eye. 6. Remove throttle body bracket attaching bolt, install lifting eye, then using suitable equipment support engine. 7. Remove lefthand transaxle mount. 8. Remove transaxle side pan upper attaching bolts. 9. Raise and support vehicle. 10. Remove lefthand front wheel and tire assembly. 11. Remove inner fender cover and position aside, then disconnect ride height sensor. 12. Remove rear transaxle mount attaching bolt. 13. Loosen but do not remove two lefthand subframe attaching bolts. 14. Remove two engine support mount attaching bolts. 15. Remove four lefthand engine support attaching bolts, then remove the engine support. 16. Position suitable drain pan, then remove remaining transaxle side pan attaching bolts and remove pan. 17. Using suitable screwdriver, place manual shift shaft in Park position. 18. Disconnect upper bulkhead electrical connector wiring retainer clip from valve body. 19. Disconnect electrical connectors. Oil Pump And Valve Body Bolt Removal 20. Remove valve body attaching bolts, then disengage linkage and remove valve body. NOTE: Do not remove oil pump cover attaching bolts. INSTALLATION 1. Install new pump and valve body to chain cover gasket. 2. Slide pump and valve body onto pump shaft. 3. Rotate pump and valve body assembly toward dash panel, then engage manual valve link with manual valve. 4. Slightly rotate pump and valve body assembly to engage oil pump shaft splines with oil pump rotor splines. Valve body should slide flush with chain cover. A suitable 7/8 inch deep well socket on crankshaft pulley may be required for complete engagement. 5. On models less anti-skid, if engagement is not as indicated in step 4, proceed as follows: a. Remove manual valve from valve body. b. Rotate assembly to allow full engagement, up to 360° . c. After full engagement, return assembly to installed position, then install manual valve.

1. Remove the idle air control (IAC) valve connector. 2. Remove the IAC valve attaching screws (1). NOTE: If the IAC valve has been in service: DO NOT push or pull on the IAC valve pintle. The force required to move the pintle may damage the threads on the worm drive. Also, DO NOT soak the IAC valve in any liquid cleaner or solvent, as damage may result. 3. Remove the IAC valve assembly (2). ^ Clean the IAC valve O-ring sealing surface, the pintle valve seat, and the air passage. ^ The IAC valve may be cleaned. Use a shop towel or parts cleaning brush to remove any heavy deposits. ^ Any shiny spots on the pintle or seat are normal and do not indicate misalignment or a bent pintle shaft. ^ If the air passage have heavy deposits, remove the throttle body for a complete cleaning. ^ Inspect the IAC valve O-ring for cuts, cracks, or distortion. Replace the O-rings if necessary. ^ When installing a new IAC valve, be sure to replace the valve with an identical part. The IAC valve pintle shape and diameter are designed for a specific application. MEASUREMENT PROCEDURE This procedure is only for installing a new IAC valve. IMPORTANT: If installing a new IAC valve, replace the IAC valve with an identical part. The IAC valve pintle shape and diameter are designed for the specific application. Measure the distance between tip of the IAC valve pintle and the mounting flange. If the distance is more than 28 mm (1.1 in), use finger pressure to slowly retract the pintle. The force required to retract the pintle of a new valve will not cause damage to the valve. INSTALLATION PROCEDURE
