1990 Mazda Miata MX-5 ProblemsTicking Noise From Valve Lash Adjusters Due to Infrequent Oil Changes
A loud ticking noise (hydraulic valve lifter noise) may be heard from the top of the engine, particularly when the engine is still cold. The noise may occur more frequently on higher mileage vehicles; Hydraulic valve lash adjusters may need to be replaced to correct this issue. Following the maintenance schedule for oil changes will also help prevent a recurrence of the noise.
The clutch slave cylinder may develop a hydraulic leak resulting in no clutch pedal pressure and the inability to shift gears.
