Valve Lash Adjustment On
1986-92 Isuzu 2.3 & 2.6L Engines
AERA member have expressed some confusion on the correct valve lash
adjustment procedure on 1986-92 Isuzu 2.3 & 2.6L engines. It appears that previous service manual information may lead a technician to an incorrect adjustment.
The service manual indicates that valve lash on the #1 cylinder should be adjusted when all timing marks are lined up. The camshaft however, is in the valve overlap position at the number one cylinder. If the adjustment is made as indicated in the manual, excessive valve lash will result. These engines are actually timed off the #4 cylinder and those valves can be adjusted when all timing marks are lined up.
To correctly adjust the valves, first look to see that the cam lobes are pointing down in the cylinder you are adjusting. The correct adjustment is made on a cold engine and is .008 for both valves on the 2.6L engine. The adjustment for the 2.3L engine is .006 for intake valves and .010 for exhaust valves.
