1990 Mazda Miata MX-5 Problems
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 engine may idle roughly or stall when it's cold because the oil pump pressure relief plunger is sticking. Failure is usually due to wear and it causes excessive oil pressure to pump up the hydraulic valve lifters keeping the valves from closing completely, which results in a loss of compression. The oil pump will need to be replaced in this case.

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. I asked myself the question do I want to work on my British cars during the week so I could drive...
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 ...
