Valve Train Noise On
1993-94 Mazda 2.0L Engines
The AERA Technical Committee offers the following information regarding a valve train noise on 1993-94 Mazda 2.0L engines. This noise can be associated with the Hydraulic Lash Adjusters (HLA).
This noise appears after the engine has been run at idle for a long period of time. The noise appears because air is entering the oil gallery. To prevent this condition from happening, Mazda had redesigned the oil pump plunger as shown in Figure 1.
HLA noise will appear at the top of the engine and is several times faster than that of the engine speed. Verify the complaint by running the engine at idle for a period of time not letting the vehicle overheat. If the HLA noise is present, replacement of the oil pump plunger is required.
To replace the oil pump plunger, remove the snap ring at the bottom of the pump as shown in Figure 1. Remove spring seat, pressure spring and the plunger. Replace the old plunger with the new plunger, Part #JF01 14 115. Reassemble the bottom of the oil pump in the reverse procedure of disassembly
NOTE: Follow instructions in the service manual for disassembly and assembly of the engine to get access to the oil pump for replacement of the plunger.
