MY TRUCK HAD 159,000 MI ON MY MAZ BEFORE THE MOTOR FINALLY WENT, THIS WAS MY FIRST VEHICLE AND I WAS EXTREMELY HARD ON IT.
I RECENTLY CARRIED THE MOTOR TO THE MACHINE SHOP, AND WHEN THEY TORE IT DOWN HE SAID THAT THE PISTON RINGS, VALVE GUIDES & VALVE SEALS WERE SHOT, PLUS IT HAD A BLOWN HEAD GASKET. THE HEAD, BLOCK CRANK AND CONN. RODS, & PISTONS WERE ALL GOOD THOUGH.
IF YOU PULL THE HEAD, I WOULD HAVE IT REWORKED, IT SHOULDN'T COST BUT @ $350-$400, AND WHILE THE HEAD IS OFF PULL THE PISTONS AND PUT NEW RINGS IN. THAT SHOULD CURE ALL OF YOU MOTOR AILMENTS, AND IT SHOULD GO ANOTHER 200,000 MI WITH PROPER CARE.
