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.Google+

Mazda MPV Ticking Noise From Valve Lash Adjusters Due to Infrequent Oil Changes
Mazda MPV Problem
Engine Affected: 3.0L V6
Average Mileage: 120,484 mi (58,000 mi - 160,000 mi)
I have owned this 1996 MPV almost a year. I had the valve ticking noise for the first few minutes the engine was running cold, and then it would go away. I changed the oil and it started doing it worse after about 500 miles on the fresh oil change. I noticed the engine was using oil, so I added a bottle of stop leak seal conditioner. The valve ticking persisted. I soon added a large 8 cylinder size bottle of Restore and there is no more ticking at all.
