200 ENGINE ASSEMBLY [213 LH] VALVE LIFTER PUSH RODS Inspection Check the push rods. Replace any push rods that have loose ends, are bent, or show signs of excessive wear.
Identification Refer to Figure 6-67. The current E7 valve lifter has no hole in the center of the stem. In conjunction with this change, the E7 inlet and exhaust (nonbrake engine) push rods have a 0.060-inch (1.524 mm) maximum flat or dimple on the ball end. The push rod part number is etched or roll-stamped on the push rod. CURRENT 369GC334
The non-current push rod should be used only with the non-current lifter. If the non-current push rod with the wide flat or dimple is used in the current valve lifter which has no center hole, it may create an undesirable wear pattern in the lifter socket. Mixing current and non-current valve lifters is permissible when using the correct lifter/push rod combination. 앫 Current push rod can be used with either valve lifter. 앫 Do not use non-current valve lifter to service current valve lifter. Only Dynatard exhaust push rods are not affected and can be used with current and noncurrent valve lifters. Dynatard intake push rods still need to be updated to current push rods when using current valve lifters.
