NHTSA Complaint #714497 — 1994 MAZDA MPV

-ALMOST EVERY TIME WE START THE ENGINE, A VERY LOUD CLACKING NOISE PERSIST FOR A FEW MINUTES AND THEN AFTER THE VAN IS WARMED UP THE CLACKING SOUND SUBSIDES TO A MINIMAL NOISE LEVEL BUT IS NEVER THE LESS STILL APPARENT. AT FIRST " STARTS" IN THE MORNINGS IT SEEMS TO BE GETTING LOUDER. IT SOUNDS LIKE THER IS NO OIL IN THE ENGINE AND THE VALVES ARE JUST CLICKING AND KNOCKING LIKE CRAZY. I CHANGE THE OIL EVERY 3-4000 MILES AND MAKE SURE IT IS CONTINUALLY FULL. I CALLED THE MAZDA MAINTENANCE DEPARTMENT AT METRO MAZDA, 1087 I-20 WEST FRONTAGE RD., JACKSON MS, 601-944-1333 AND WAS TOLD BY ONE OF THE MECHANICS NOT TO WORRY ABOUT IT , BECAUSE MOST OF THE MPV'S HAVE THAT PROBLEM.
