1999 CHEVROLET VENTURE MINIVAN INTAKE MANIFOLD GASKET FAILED CAUSING DEXCOOL COOLANT TO LEAK INTO THE ENGINE AND MIX WITH THE OIL. A SIMPLE INTERNET SEARCH FOUND LITERALLY THOUSANDS OF OTHER FOLKS WITH THE SAME PROBLEM. GM CUSTOMER ASSISTANCE DENIES A PROBLEM. IT COSTS AN AVERAGE OF $650-$1000.00 TO FIX THIS GASKET WITH NO ASSURANCE THAT A NEW IMPROVED GASKET IS IN PLACE. THIS SEEMS TO HAPPEN SHORTLY AFTER THE 36,000 MILES WARRANTY COVERAGE IS UP.

INTAKE MANIFOLD GASKET ON THE 3.4L ENGINE IN MY 1999 CHEVROLET VENTURE FAILED. THIS IS A PERVASIVE KNOWN PROBLEM WITH THE 3.4L ENGINE PRODUCED AND SOLD BY GM. GM HAS HAD A NATIONWIDE BACKORDER ON THE GASKED INVOLVED INDICATING REDESIGN DUE TO POOR INITIAL DESIGN. I HAD TO WAIT 4 MONTHS FOR THE GASKET TO BE DELIVERED AND THERE WERE 2 OTHER VENTURES IN THE REPAIR FACILITY UNABLE TO BE REPAIRED OR DRIVEN DUE TO THE BACKORDER. MY COST FOR REPAIR WAS $538. OTHERS HAVE HAD TO PAY OVER $4,000 DUE TO ENGINE FAILURE. THIS SHOULD BE INVESTIGATED AND GM MADE TO CONDUCT A NATIONWIDE RECALL/REIMBURSEMENT OF SAID REPAIR COSTS. IF YOU DESIRE I WILL PROVIDE MY REPAIR INVOICE. DUE TO THE PART FAILURE AND WAITING ON GASKET DELIVERY AND REPAIR, I MAY HAVE HIDDEN ENGINE DAMAGE THAT MAY SURFACE AT A LATER TIME.*JB

I UNDERSTAND FROM MY MECHANIC THAT THIS IS A COMMON PROBLEM AND THAT GM IS AWARE OF IT. GM SHOULD BE REQUIRED TO REPAIR THIS DEFECT AS IT COULD LEAD TO A BLOWN ENGINE WHICH WOULD BE VERY DANGEROUS IN TRAFFIC.*JB

I KNOW OF ONE OTHER PERSON THAT HAS EXPERIENCED THE SAME PROBLEM WITH THEIR CHEV. VENTURE. I BELIEVE THIS IS DESIGN FAULT AND SHOULD BE COVERED BY GENERAL MOTORS.

I HAVE DEX-COOL COOLANT IN MY OIL. IT SEEMS THAT I HAVE A BAD GASKET, AND THAT THERE ARE A LOT OF OTHERS WHO ALSO HAVE THIS PROBLEM WITH LEAKING GASKETS (WHICH HAVE BEEN REDESIGNED). I THINK THAT GM SHOULD FIX MY CAR PRIOR TO TOTAL CATASTROPHY OF ENGINE FAILURE WITH MY LESS THAN 1-YEAR OLD CHILD ON BOARD.

COOLANT LEVEL KEPT DROPPING AND THE BRAKES FELT SPONGY. TOOK TO LOCAL DEALER AND FOUND THAT MAINFOLD GASKET WAS LEAKING AND NEEDED TO BE REPLACED AND THE REAR CYLINDERS WERE LEAKING AND NEEDED TO BE REPLACED. REPAIR COST $1078.00 FOR BOTH. THIS VAN ONLY HAS 56,000 MILES. GOOD TO SEE THAT OTHERS ARE HAVING PROBLEMS WITH THESE COMPONENTS, MAYBE THE MANUFACTURER NEEDS TO RECALL AND FIX THESE PROBLEMS. A VEHICLE OWNER SHOULDN'T HAVE TO SPEND THIS KIND OF MONEY(FOR THESE KIND OF REPAIRS) AND RISK THEIR FAMILY ON THE ROADSIDE ON VEHICLES WITH THIS FEW OF MILES AND AGE. I'VE ALSO HAD AN AIR BAG WARNING LIGHT ON FOR MOST OF THE TIME THAT I'VE HAD THE VEHICLE. IT WAS WORKED ON A COUPLE OF TIMES DURING THE WARRANTY PERIOD. THE DEALER SAID IT WAS AN AIR BAG SENSOR PROBLEM. THIS VEHICLE HAS FRONT AND SIDE AIR BAGS. I HOPE THE AIR BAGS DEPLOY IN CASE OF AN ACCIDENT.
