1999 Chevrolet Venture engine problems

ENGINE

IN SEPTEMBER OF 2013 I NOTICED OIL IN COOLANT RESERVOIR. TOOK TO THE MECHANIC. CLOSER INSPECTION SHOWED HEAD GASKETS WERE DESTROYED. HAD THE HEAD GASKET REPLACED AND THE COOLANT FLUSHED OUT AS WELL AS CHANGED ALL COOLANT HOSES, WATER PUMP, AND THERMOSTAT TO THE TUNE OF $900.00 DOLLARS. VEHICLE ONLY HAS 84000 MILES ON IT. PURCHASED NEW IN 1999. USED THE VEHICLE DAILY FOR FOUR MONTHS WHEN THE TEMPERATURE GAGE STARTED FLUCTUATING FROM HOT TO COLD AND FOUND THERE WAS VERY LITTLE HEAT. VEHICLE WOULD THEN IDLE ROUGH. BROUGHT BACK TO THE MECHANIC AND IT APPEARS THE SAME ISSUE IS OCCURRING. YOU'VE GOT TO BE KIDDING ME. ANOTHER $800-$1000 NO WAY. MECHANIC ADVISES THIS IS COMMON FOR VENTURES. THANKS CHEVY LOOKS LIKE I'LL BE SHOPPING FOR A HONDA.

PURCHASED VEHICLE BRAND NEW. MANIFOLD GASKET LEAK AT 35,000 MILES REPAIRED BY GM. FAILED AGAIN AT 70,000 MILES BUT GM WOULDN'T COVER THE COST, PAID $900 OUT OF POCKET. NOW AT 112,000 MILES AND SUSPECT THAT IT IS IN NEED OF REPLACEMENT AGAIN. THE LIFTERS ARE ALSO MAKING NOISE. THE MECHANICS ARE TELLING ME THAT THIS IS A VERY COMMON PROBLEM. GM NEEDS TO TAKE RESPONSIBILITY FOR THIS DESIGN FLAW IN THEIR ENGINE. THE GOVERNMENT NEEDS TO STEP IN AND ORDER A RECALL.

TL*- THE CONTACT OWNS A 1999 CHEVROLET VENTURA. THE CONTACT STATED THAT THE VEHICLE HESITATES WHEN SHIFTING INTO SECOND GEAR. SHE REPLACED THE TRANSMISSION, BUT THE FAILURE WAS STILL PRESENT.ALSO THERE WAS A PUDDLE OF WATER ON THE FRONTAL FLOOR BOARD. THE VEHICLE WAS TAKEN TO A LOCAL REPAIR FACILITY AND A MECHANIC REPLACED THE HEATER CORE. IMMEDIATELY AFTER THE REPAIR THE ENGINE OVERHEATED. THE VEHICLE WAS RE-INSPECTED IN WHICH THE MECHANIC CONCLUDED THAT THE HEAD GASKETS FAILED. THE VEHICLE HAS NOT BEEN REPAIRED. THE FAILURE MILEAGE WAS 100,000. THE CURRENT MILEAGE WAS 162,000.

ENGINE AND ENGINE COOLING:ENGINE

DEXCOOL ANTIFREEZE DETERIORATED MY INTAKE GASKETS OF MY 99 CHEVY VENTURE, SLUDGED UP MY ENGINE AND CAUSED MY CAR TO OVERHEAT AND LEAK DEXCOOL CONTINUOUSLY. THE DEALER JUST TOLD ME SORRY BUT IT WILL BE ABOUT 1500 TO 2000 TO REPAIR. THAT ANTIFREEZE WAS SUPPOSED TO BE NEVER CHANGED AND WORK UNTIL 150K MILES. MY VAN IS A LEAKING RELIABILITY PROBLEM THAT COULD STRAND US ON THE ROAD BECAUSE OF THE DEX COOL THEY PUT IN THE FACTORY. THERE WILL BE A RECALL IF YOU INVESTIGATE THIS. THE PROBLEM IS ALL OVER THE WEB AND THERE IS A CLASS ACTION SUIT ABOUT IT IN CALIFORNIA. IT AFFECTS HUNDREDS OF THOUSANDS OF PEOPLE.

INTAKE GASKETS LEAKING, UPPER AND LOWER. CAUSED OIL TO BE CONTAMINATED WITH ANTI FREEZE AND ANTI FFREEZE TO BE CONTAMINATED WITH OIL. GM HAS SINCE CHANGED THE GASKETS TO A DIFFERENT TYPE OF MATERIAL. MECHANIC STATED THAT THIS PROBLEM IS COMMON WITH THIS TYPE OF VEHICLE.

THIS WILL BE A LIST OF MOST OF THE PROBLEMS. I HAVE COMPLAINED OF SMELLING ANTI-FREEZE SINCE I PURCHASED THE VAN NEW. IT CURRENTLY HAS 94K ON IT AND I HAVE DONE ALL SCHEDULED MAINTENANCE ON IT. I THINK THE CLOCK WORK OIL CHANGES IS THE ONLY REASON IT STILL RUNS. MANIFOLD GASKETS, INTAKE, HEAD...HAVE BEEN REPLACED TWICE AND NEED IT AGAIN, REALLY BAD. BUT I JUST DO NOT HAVE 5-800 BUCKS LAYING AROUND TO DO A GASKET JOB AGAIN SINCE I JUST DID IT A YEAR AGO. THE ANTI-FREEZE DILUTING THE OIL HAS MESSED UP A COUPLE PISTONS. THEY SLAP VERY BAD OK HERE IS MY LIST (I HAVE DEALER INVOICES FOR EVERYTHING FIXED THE FIRST TIME AND RECEIPTS FOR PARTS AND LABOR THE SECOND TIME, OR MY HUSBAND GOT SICK OF PAYING FOR THE SAME CRAP SO HE WOULD FIX THINGS) (HE IS IN THE AUTOMOTIVE TESTING AND DESIGN FIELD)

THE ENGINE IN MY 1999 CHEVY VENTURE VAN JUST WENT OUT. THE VAN HAS LESS THAN 90,000 MILES ON IT. MY PARENTS 1999 VENTURE DID THE SAME THING AT APPROXIMATELY THE SAME MILEAGE 2 YEARS AGO. IS THERE A PROBLEM WITH THE ENGINES IN THE 1999 VENTURE VANS?

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE

WE HAVE A 1999 CHEVY VENTURE MINIVAN WITH 50,000 MILES ON IT. WE STARTED HAVING PROBLEMS ABOUT A YEAR AND A HALF AGO WITH IT. AFTER MANY TRIPS TO THE MECHANIC, WE FINALLY FOUND THE MAIN ISSUE CAUSING THE NUMEROUS PROBLEMS. A LEAK IN THE INTAKE MANIFOLD LEAKING COOLANT INTO THE ENGINE OIL. THE GM PART IS PLASTIC. IT IS A SMALL PART, BUT TAKES 7.5 HOURS TO FIX, SO THE AVERAGE COST TO FIX IT IS $800!!. THERE ARE LITERALLY THOUSANDS OF COMPLAINTS ABOUT THIS PART USED BY GM. THERE IS A PETITION WITH OVER 9,000 SIGNATURES!! ITS TIME FOR GM TO RECALL THE PART AND MAKE THINGS RIGHT FOR THEIR CUSTOMERS ESPECIALLY WHEN IT IS USUALLY FAMILIES WITH SMALL CHILDREN RIDING IN THESE GM MINIVANS.

MY WIFE WITH MY 4 SMALL CHILDREN WERE ENTERING MO HWY 412 WHEN THE VEHICLE STARTED STALLING AND QUIT. WHEN THE VEHICLE QUIT IT WAS PARTIALLY ON THE HWY AND PARTIALLY ON THE TURN FROM WHERE SHE WAS EXITING. WHILE SHE ALONE WAS TRYING TO PUSH THE VEHICLE OFF THE HWY A TRACTOR TRUCK AND TRAILOR ALMOST RUN THEM OVER. TAKE IN MIND THAT WHEN THESE VEHICLES DIE THEY HAVE NO BRAKES OR POWER STEERING. WHEN I HAD THE VEHICLE CHECKED OUT IT SEEMS THAT IT HAD A INTAKE VALVE GASKET BLOWN LEAKING DEXCOOL INTO THE OIL AND BROKE THE CAMSHAFT. AT THIS TIME I CAN'T AFFORD TO HAVE THE VEHICLE FIXED BECAUSE FROM THE RESEARCH I'VE DONE IT WILL COST $4,000 TO $5000 TO GET THE VEHICLE FIXED.

THE CAR HAS BEEN RUNNING LOW ON RADIATOR FLUID, BUT WE COULD NOT FIND ANY VISIBLE LEAKAGES. WE HAVE BEEN REPLINISHING THE FLUID. WE DID NOT THINK ANYTHING MAJOR. ON A FRIDAY, WE STARTED TO HEAR A KNOCK IN THE ENGINE. WE WERE TOLD TO HAVE THE OIL CHANGED/LOOKED AT. AFTERWARDS, THE NOISE CONTINUED EVEN LOUDER. WE HAD THE CAR IMMEDIATELY TOWED. THE PROBLEM INVOLVED THE LIFTERS AND THE INTAKE GASKET. (BOTH PROBLEMS ARE RELATED.) I RESEARCHED AND MANY OTHERS HAD THE SIMILAR PROBLEMS WITH THE INTAKE GASKET. REPAIR FOR ALL WILL BE $1,000.

I'VE HAD A 1999 CHEVY VENTURE SINCE NEW. I'VE HAD TO REPLACE THE INTAKE MANIFOLD GASKET, UPPER AND LOWER RADIATOR HOSES AT 69500 MILES. REPLACED THE THERMOSTAT AT 78400 MILES. AT 78500 MILES I HAD TO REPLACE BOTH HEAD GASKETS,INTAKE GASKET AND PLENUM GASKET, BOTH VALVE COVER GASKETS AND SEVERAL COLLAPSED LIFTERS, AND THE CYLINDER HEADS NEEDED TO BE RECONDITIONED. THESE REPAIRS COST ME THOUSANDS OF DOLLARS. SOMETHING IS SURELY NOT RIGHT WITH THIS ENGINE.

INTAKE MANIFOLD GASKET FAILED AT 91,000 MILES. THIS IS THE SEOND TIME THIS GASKET HAS FAILED ON THIS CAR. THE FIRST TIME (3 YEARS AGO, I THINK) WAS REPLACED BY GM UNDER WARRANTY. THIS PROBLEM IS ENDEMIC TO THIS (3.4 V6 AND THE GM 3.1 V6) ENGINE. GM SHOULD RECALL AND FIX THESE FOR FREE.

THE LOW COOLANT LIGHT CAME ON IN MY 1999 CHEVROLET VENTURE LS (THAT I PURCHASED IN JANUARY OF 2004), THE ENGINE STARTED MAKING A HORRIBLE KNOCKING NOISE, AND THEN FROZE UP WHILE DRIVING DOWN THE HIGHWAY. AFTER HAVING TO HAVE IT TOWED AND LOOKED AT BY 2 MECHANICS, THE DIAGNOSIS WAS THAT THE INTAKE MANIFOLD GASKET WAS DEFECTIVE AND ALLOWED COOLANT TO LEAK INTO THE ENGINE, CAUSING THE ROCKER ARMS TO QUIT WORKING, THE VALVES TO BEND AND THE CAM SHAFT TO BREAK IN HALF. THE COST OF A REBUILT MOTOR AND LABOR TO INSTALL IT ADDS UP TO $4,300. GM DOESN'T KNOW IF THEY CAN HELP OR NOT.
