ENGINE AND ENGINE COOLING:ENGINE
LIFTERS & ROCKER ARMS REPLACED 3 TIMES - CARBON BUILD UP WAS NEVER FIXED CAUSES ENGINE TO NEED REPLACEMENT.
NHTSA complaint #738807 — an unverified report by a vehicle owner.
ENGINE AND ENGINE COOLING:ENGINE
THIS PROBLEM WITH THE LIFTERS HAS BEEN REPORTED TWO SEPARATE TIMES. BOTH TIMES WE WERE GIVEN A MAJOR RUN AROUND IN ORDER TO GET THIS ISSUE TAKEN CARE OF. ON THE FIRST VISIT WERE TOLD THAT KNOCKING WAS NORMAL FOR A ENGINE TO DO. WHICH I STRONGLE DISAGREED WITH. AFTER GOING INTO THE ENGINE IT WAS FOUND THERE THERE WAS SOME COLLAPSED LIFTERS. SOON AFTER THE REPAIR THE PROBLEM RESURFACED, THIS TIME SPACERS WERE INSTALLED. I WAS TOLD THAT NOT ENOUGH OIL WAS REACHING THE LIFTERS. AFTER THIS THE KNOCKING WAS GONE FOR A LONG PERIOD OF TIME AND I THOUGH THE PROBLEM WAS TAKEN CARE OF. UNTILL WE MOVED TO GEORGIA IN JULY OF 98 THE PROBLEM HAS BEEN WITH US UNTILL PRESENT. I CAN SAFTLY SAY THAT I TAKE VERY GOOD CARE OF THE VAN THE OIL IS CHANGED ON A 2000 MILE CYCLE SO I WOULD THINK THAT THE OIL SHOULD BE ABLE TO REACH THE LIFTERS FINE. EVEN THOUGH I WAS TOLD BY THE MAZDA DEALER THAT THE KNOCKING NOISE WOULD NOT CAUSE DAMAGE TO THE ENGINE, I HAVE TO DISAGREE. THE CAM SHAFT HAS TO HAVE SOME KIND OF WEAR AS WELL CONSIDERING THATS WHAT THE PUSHES THE LIFTERS UP.

ENGINE AND ENGINE COOLING:ENGINE:GASOLINE
-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.
