: the contact stated the engine would not start after the vehicle was parked overnight. Initially, it was suspected the battery was discharged and the battery was charged for twenty minutes. Afterwards, the contact attempted to start the vehicle, with the key in the ignition, and the intake manifold exploded. A large fireball along with pieces of the intake manifold and the engine cover shot out of the underhood area. The vehicle was towed to a dealer for inspection. The dealer determined the backfiring occurred due to the contact starting the engine while applying the accelerator pedal. The manufacturer was alerted.

: the contact stated while driving 45mph, the engine stalled and the check engine light illuminated. The temperature gauge of the engine also elevated and the engine was turned off. The vehicle was towed to an independent repair shop for inspection. The mechanic determined the intake manifold, head gaskets, and the engine cooling system needed to be replaced. The dealer and manufacturer have been alerted and agree the vehicle is included in a customer satisfaction program, # 03034, concerning the engine and engine cooling. However, both refuse to repair the vehicle without charge because the campaign expired.

The contact stated the turn signal worked intermittently. This has been occurring for approximately one year. When the turn signals were not working he could press the hazard light switch and the turn signals would activate. Nothing has been done to correct the problem. During an oil change a mechanic determined that the lower intake manifold gasket was leaking. The manufacturer was contacted and offered to pay for half of the repairs. The repairs have not been made. The replaced the hazard switch warning light. Updated 01/11/06.

Intake manifold gasket leaking. Low coolant light came on. Repair is approx $900 at the dealer, beardmore Chevrolet. In checking for a cheaper repair price, several mechanics stated they have replaced lots of these on the Impala. Sounds like a defect. Repair is being done today, 2 Dec 04 at beardmore Chevrolet, bellevue Nebraska.

"plastic" by pass tube from intake manifold to water pump cracked, causing antifreeze to leak out at a rapid amount. Can't believe that the tube is made out of plastic since it is in contact with the intake manifold which is very hot. Fortunately my wife and son were just around the corner from our house and not on the trip to Ohio which was planned. Only going about 10 mph when noticed a gurgling sound. Got out of car and saw fluid leaking. Came back to house and I checked it out and found that the plastic tube above the water pump leading into the manifold was indeed the problem. Took car to Chevrolet dealership. They replaced the by pass tube at a hefty cost of $262.38.

Intake manifold gaskets leaking. After speaking with numerous people and a GM service member it seems very clear that there is a problem with the gaskets on the GM 3100 and 3400 engines.

Failed manifold gaskets on 2000 3.4 engine used in most GM cars. GM is insufficiently dealing with or trying to keep from becoming a recall. Mine was the 5th 2000 Impala this week with the same problem (its only Wednesday). Expect to pay $250+ for repair. Mechanic says GM installed wrong size manifold bolts during assembly (dealer repair kit comes with correct, but different, bolts).

2000 Chevrolet Impala. Premature failure of the intake manifold gasket. The leak appears in the gasket that is directly next to the stove pipe from the exhast manifold. It appears the high temperature from the the stove pipe is deteriorating the gasket in the intake manifold. This has every indication of an engineering defect due to the number of complaints on this same problem. Other similar problems were discovered in Impala with VIN type K mine is type E see tsb 03034.

Intake manifold gaskets went costing over $600 dollars to replace at local Chevy dealership, assumed this was just a slight problem but I see it happening to a lot of Impala... I know there's been a recall but not on the 3.4's something needs to be done about this since Chevy knows there is a major problem here...
