NHTSA Complaint #10125235 — 2000 CHEVROLET VENTURE

I HAVE A CHEVY VENTURE 2000. FOR THE LAST 6 MONTHS I HAVE HAD OIL SPOTS ON THE GROUND IN THE GARAGE, AND HAVE HAD TO KEEP FILLING UP THE COOLANT RESEVOIR TANK FOR A FEW WEEKS NOW. I HAD THE CAR CHECKED AT THE DEALER FOR THE OIL SPOTS AFTER HAVING THEM DO AN OIL CHANGE MONTHS AGO. THEY TOLD ME NOT TO WORRY ABOUT THAT SMALL AMOUNT OF OIL. HOWEVER WHEN I TOOK IT IN TO GET CHECKED WHY I WAS HAVING TO ADD COOLANT THEY FOUND THAT THE INTAKE MANIFOLD GASKET WAS LEAKING. IT COST ME $600.00 TO HAVE THIS REPAIRED. MY VAN HAS 86K MILES ON IT. IT HAS HAD THE GASKET REPLACED TWICE NOW. I HAVE RESEARCHED INFO FOR THIS PROBLEM AND HAVE FOUND MANY OTHER VEHICLE OWNERS OF THE 3.1L AND 3.4L MOTORS IN GM'S HAVING THE SAME PROBLEM. WHY DOES THIS CONTINUE TO BE A PROBLEM? THIS HAS TO BE DAMAGING THE ENGINE HAVING COOLANT BEING ABLE TO LEAK INTO IT. THE SERVICE STATION I WENT TO DOES SEVERAL OF THESE A MONTH ON 1998 TO 2001 MODELS WITH THESE ENGINES. THEY TOLD ME THAT THERE IS A FLAW WITH EITHER THE GASKET OR THE DEX COOL THAT CORRODES THE GASKET.
