1990 Mazda Miata MX-5 Problems

Ticking Noise From Engine Due to Sticking Valve Lash Adjusters

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.

A Leak May Develop From the Clutch Slave Cylinder

The clutch slave cylinder may develop a hydraulic leak resulting in no clutch pedal pressure and the inability to shift gears.

Engine Misfire Due to Engine Oil on the Spark Plug Wires

Failure of the valve cover gasket can allow engine oil to leak onto the spark plug wires and damage them. The engine will run poorly (misfire) if the spark plug wires fail.

I bought my '90 Miata new. It has been and still is a great car. Currently has 86k miles on the odometer. It has never had mechanical problem in all those miles and 22 years. I replaced the top about 2 years ago. New top has glass back window (much better than original). I only wish I had paid an extra $1,400 for the removable hard top the dealer had at the time.
I have owned my 90 since 95. When I bought it it had 30,000 miles on it, now has 130,000. Love this car. Do the scheduled maintenance and give it the TLC it deserves and these cars will be there for you. Radio is a problem, had to replace it in 2001. Paint peeled starting in 1997, have talked to other owners, same problems. I am 6'3" with a 32" inseam and 300 Lbs, this car fits me better ...
As the former owner of half a dozen British sports cars, I came across a great deal on a high mileage slightly beat up Mazda Miata. What a surprise! After doing several minor repairs and catching up on neglected maintenance by the previous owner I started to drive and enjoy my Miata more and more.
