Manifold/header/muffler/tail Pipe problems of the 2002 Chevrolet Impala

On April 9th of 2017, our 2002 Impala LS was brought in to have the vehicle serviced due to this recall: these vehicles have a condition in which drops of engine oil may be deposited on the exhaust manifold through hard braking, which may result in an under hood fire. This work was done in April 2017: dealers will replace the engines front valve cover and front-valve-cover gasket with new parts of an improved design and remove the engines plastic cover and plastic oil-fill-tube extension. Summer of 2017 we had the oil and filter replaced, and afterwards lots of smoke came from engine. We thought the mechanic had simply spilled some oil on the engine. Summer of 2018 oil and filter was changed and smoke from the engine compartment, we again thought the mechanic had spilled some oil on the engine. In March of 2019 the vehicle was parked, facing downhill at an above average angle, and oil began to seep out of the engine and burn of on the hot exhaust manifold lots of smoke and potential fire hazard. The vehicle was returned to bob mccosh, who had performed the original gasket replacement in 2017, to have the original recall work inspected. Upon inspection a piece of gasket, about 2 to 3 inches long, was found to be protruding from between the valve cover and the engine. Upon further inspection of this gasket, the edge of the gasket visually appeared to have been caught by the bolt as it was tightened and this either tore the gasket or weakened it sufficiently so that the gasket failed. Said gasket is currently in my possession. We know it failed before the oil/filter change in the summer of 2017, because of the amount of smoke that issued from the engine compartment afterwards. This recall repair lasted far less than the 12month/12,000 mile warranty. The vehicle, today April 2019, still has less than 10,000 miles since the original recall work was done in March 2017.

Chevrolet Impala engine cold parked in driveway started the car and the engine exploded: fire started under hood. The manifold exploded.

The car was constantly stalling in low speed or starting from a stop in d drive. The transmission was not shifting properly. Car had stalled a few times in traffic, becoming a hazardous situation. Car was overheating. Car had been serviced a week ago at aaa repair center, eatontown, NJ for oil leak from gasket of the manifold.

Model years affected: 2000, 2001, 2002, 2003, 2004, 2005 engines affected: 3. 4l v6, 3. 8l v6 average mileage: 108,315 mi (13,756 mi - 198,000 mi) verified the intake manifold gasket can develop external engine oil or coolant leaks. In some cases the failed gasket will leak coolant internally. The manifold gasket will need to be replaced to correct this issue. Thousands of cars are affected. These vehicles need to be recalled and fixed.

The contact owns a 2002 Chevrolet Impala. The contact inspected the vehicle and noticed that the rear engine valve cover and gasket leaked oil onto the exhaust manifold. A strong burning odor emitted inside the cabin. There were no flames visible. The vehicle was serviced under NHTSA campaign number: 15v701000 (engine and engine cooling). The manufacturer was not notified of the failure. The approximate failure mileage was 110,000.

My son went to jump start the car and when he tried to start it the engine blew up . The intake manifold flew off in multiple pieces. Had car towed to my mechanic and found out the cylinder was dead due to the explosion. Though well the car had a lot of miles, so I thought it was just its time. So we decided to buy a re-manufactured motor because we had put some work into the car and my son and I though that would be a good choice. Everything was great with the new motor till November 30th 2014 when we needed to jump start the car, and the engine blew again this time taking out the fuel line along with the new intake manifold and the engine cover. The car starts on fire and luckily the flying parts missed my sons girl friend by inches as they flew by her. So I know now somethings up. And I find that gm had defective fuel regulators that were recalled (04v090000 recall#) on the 2000 models with the 3800 series 2 engine. Now I know why my engine blew because the fuel regulators are poor design. No car no matter how old are how many miles should blow an engine when you jump start it. Batteries yes engines I would think never but what happen to me is the same as the recall notice and I am thank full no one was hurt.

Intake manifold leak, replaced the engine. Intermediate no starts, vehicle cuts off in 5 mins of driving, turn signals works sometimes. . Car is dangerous to drive and I have almost had several accidents because of the issues.

The contact owns a 2002 Chevrolet Impala. The contact stated that the low coolant indicator illuminated. The contact refilled the coolant, but it had leaked out by the following day. The failure occurred on numerous occasions. An independent mechanic stated that the intake manifold gasket needed to be replaced. The vehicle was not repaired and the manufacturer was not notified. The approximate failure mileage was 120,000.

2002 chevy Impala LS v6 engine, required to have intake manifold gasket replaced. The gasket had dissolved and was allowing oil and coolant to leak onto the engine block, and mix within the engine. Mechanic advised that this is a known issue with the dex coolant that gm uses, and deteriorates the gasket.

The contact owns a 2002 Chevrolet Impala. The contact stated that the vehicle would continuously overheat and the coolant warning light would illuminate on the instrument panel. In very high temperatures, the vehicle would hesitate to start and would often stall. The contact believed that there was an issue with the intake manifold. The manufacturer stated that the exhaust manifold could possibly be leaking water. There were no recalls for the failure. The VIN was unknown. The current and failure mileages were less than 126,000.

Leaking upper and lower intake manifold gaskets,car overheating and running poorly. Occured at 55,000 miles and again at 110,000 mi. . Gaskets replaced for 900. 00 each time,old gaskets aere available.

I noticed the car was running hotter than normal so I had it checked out and the intake manifold was leaking, had it repaired and I recently had to have it repaired again @106,954 miles because it was leaking again in the same place.

Owner of 2002 chevy Impala that has an intake manifold leak. Family member also had an Impala, 2003, and had the same issue. Why is this such a problem? when I searched the issue online I found many owners that had the same issue. Gm needs to issue a recall on this problem and have proper gaskets installed in their cars. This car is not a cheap car, and to have these problems is a sign of a poor quality.

The intake manifold gasket is leaking. It poses a fire hazard if the car is overheated which could pose health threats to those in the car and others outside of the car. The car is a 2002 chevy Impala with 71,000 miles. This car has had regular maintenance and is good condition. There have been several things fixed over the past two years. We have spent over $3,000 fixing everything. We cannot afford to fix yet another problem. This car should not be facing these problems at such an early stage.

I have twice had to take my 2002 Chevrolet Impala to the shop (resulting in lost time from work and unnecessary repair bills) because the low engine coolant warning light comes on and stays on even though the coolant level is full. The repair shop has twice found oil in the coolant, despite having flushed the cooling system and installing a new low coolant level sensor at a cost of $165. Now I am told that this is a common problem with the intake manifold gasket on this type of vehicle and that it will cost around $900 to fix it properly. This car had only 20,580 miles on it when the problem was first attended to and now still has only 21,557 miles.

Started experiencing engine pulling/hesitation, then my engine would idle at 2,000 rpms and increase to 3,000. Come to find that there is a hole in the intake manifold not knowing why. I only had the car for 4 months and put a little over 7,000 miles on it.

: the contact stated while driving there is a smell of antifreeze. The vehicle was taken to an independent repair shop; the problem was determined to be a leaking intake manifold gasket. The vehicle has not been to the dealership nor has the manufacturer been alerted.

Valve cover leaks oil onto manifold . When engine is hot you can smell the oil burning on the manifold. This has been going on since purchasing the vehicle. We received a recall notice #15757 notifying us of this problem in December 2015. The dealer tells us gm doesn't have the parts to repair the defect but they dealer would repair defect and bill us and gm would reimburse us for repair. If the dealer has the parts to repair defect why not just do it? recall notice warns us not to park vehicle in garage because of fire danger.

2002 Chevrolet Impala experienced a problem with stalling and misfiring. ** answer required***. This was an intermittent problem. A hole burnt through the upper intake manifold, resulting in excessive amounts of air to enter the system. The clogged converter was the source of the problem which allowed excessive back pressure to build up in the system and gases that were much hotter than normal entered the manifold.

Engine stalls, remoteless key entry doesn't work, coolant leaking.

Consumer noticed that every week, he had to fill the coolant reservoir. The vehicle was taken to an independent repair shop, and mechanic determined that intake manifold cracked and coolant spilled inside the engine.

While driving, the vehicle overheated and smoke emitted from the front of the vehicle. The consumer was able to maintain control of the vehicle, and drove it to the dealer for inspection. The mechanic determinedthat the intake manifold gaskte had failed.

Two months after I bought the car both my headlights fogged over. They cost $250 a piece to replace (have not yet replaced). About a month later a computer chip that controlled my lights, locks, windows, interior lights, and stereo went bad and that cost $353 to replace. Soon after that I noticed that my car felt like it moved back and forth when I drove it, and the steering wheel was very loose when I turned. I didn't think it was a very big deal but took it into the shop to have it looked at. I took it in and found out that I was missing 2 bearings on my suspension which put pressure on my drive shaft(not sure about actual terminology here not sure if it was drive shaft or steering column) causing my rack and pinion to go bad. That cost $1100 to fix. So now I am $1453 into having my car repaired for things that should never have gone bad in the first place. Today (may 9th 2005) I found out that my intake manifold has gone bad and I can smell burning antifreeze when I drive, and my coolant sensor is bad. To fix those two things is going to cost me $840. I should also mention that I have checked this car out on carfax. Com there was only one previous owner and nothing signifigant as how it was treated. I purchased this car at 34,000 miles and it now has 53,000 miles. This car has been nothing but problems since I bought almost 2yrs ago. I have called gm customer service 3 times now, and each time I am given the same answer "I am sorry ms. . . . There is nothing we can do for you at this time. . . ". Gm needs to get their act together and start making cars that are worth what they sell them for. Had I known how gm made vehicles with bad parts and refuse to back them up, I would never have bought the vehicle that now sits in my garage.

Consumer smelled anti freeze on the outside of the vehicle when the weather became cold. This was due to the intake manifold leaking anti freeze.
