FAILURE OF THE INTAKE MANIFOLD GASKET.
AFTER THE 2ND VALVE SPRING BROKE, I WAS TOLD THAT THE VALVES WERE SEIZING UP AND A NEW ENGINE WOULD BE REQUIRED. ALL OF THIS WAS CAUSED BY THE BAD DESIGNED MANIFOLD GASKET THAT CAUSED COOLANT TO GO INTO THE OIL. AFTER SPENDING OVER $1,000 SINCE 4-29-03, I FINALLY HAD TO TRADE IN FOR ANOTHER VEHICLE. I DIDN'T HAVE BETWEEN $4,000 AND $5,000 FOR A NEW ENGINE, WHICH ON A '96 MODEL WOULD NOT HAVE BEEN WORTH IT. I COULD HAVE GOTTEN A USED ENGINE, BUT ALL OF THEM HAVE THE SAME MANIFOLD GASKET AND THIS WOULD HAVE COST APROXIMATELY $2,000. I'VE HAD NOTHING BUT PROBLEMS WITH THIS VAN. GENERAL MOTORS SHOULD HAVE TAKEN CARE OF THIS AS A RECALL, BUT I GUESS IT WAS TOO EXPENSIVE FOR THEM TOO.
