The engine lubrication system includes many small passages. Dirty or contaminated engine oil may con- tain microscopic particles that can clog these passages. If the oil supply to the hydraulic lash adjusters (HLAs) on the 2.2 liter SOHC engine is blocked by this debris, oil pressure and supply to the HLAs will drop. A ticking noise from one or more HLA may result. This article addresses the procedure from disassembling the rocker assemblies and HLAs to exam- ine for blockage or other damage.
Engine Oil Pressure Measurement
Low oil pressure may also cause noisy HLAs. Use the following proce- dure to measure the oil pressure before further disassembly. Remove the generator from its bracket. Disconnect the connector and terminal from the generator. Remove the v-belt cover. Loosen the lock bolt and slider bolt, and remove the gener- ator v-belt. Remove the generator lock bolt. Remove the generator bolt. Disconnect the connector from the oil pressure switch. Remove the oil pres- sure switch from the engine cylinder block. Connect the oil pressure gauge hose to the engine block. Start the engine, and measure the oil pressure.
