Installation Procedure

WARNING: This page is about a different variant/trim than selected.
    NOTE: After cylinder block, head, or lifter replacement, it will be necessary to allow the engine to idle for 3-5 minutes. If the lifters are noisy, warm the engine up at less than 200 RPM. After the coolant temperature has reached approximately 85°C (185°F), cycle the engine RPM from idle to 300 RPM for approximately 10 minutes or drive the vehicle 8 kilometers (5 miles) to purge the air. If the air cannot be purged, the faulty lifters will have to be replaced.
    NOTE: Lifters that are pumped up may cause PCM misfire codes to set. Continue to operate the engine until the lifters bleed down. Using the scan tool, clear the codes and malfunction history.
    NOTE: If a valve seal is removed after it has been installed, it must be discarded. The valve stem lock groove will cut the seal's lip during removal. Use extreme care when installing valve retainers and do not damage the valve stems.
