Content Summary :
The engine lubrication system includes many small passages. Dirtyor
contaminated engine oil may con-tain microscopic particles that canclog
these passages. If the oil supplyto the hydraulic lash adjusters
(HLAs)on the 2.2 liter SOHC engine isblocked by this debris, oil
pressureand supply to the HLAs will drop. Aticking noise from one or
more HLAmay result. This article addresses theprocedure from
disassembling therocker assemblies and HLAs to exam-ine for blockage or
other damage. Engine Oil PressureMeasurement Low oil pressure may also
cause noisy HLAs. Use the following proce-dure to measure the oil
pressurebefore further disassembly. Remove the generator from its
bracket. Disconnect the connector andterminal from the generator.
Removethe v-belt cover. Loosen the lock boltand slider bolt, and remove
the gener-ator v-belt. Remove the generator lockbolt. Remove the
generator bolt.Disconnect the connector from the oilpressure switch.
Remove the oil pres-sure switch from the engine cylinderblock. Connect
the oil pressure gaugehose to the engine block. Start theengine, and
measure the oil pressure.
