Manifold/header/muffler/tail Pipe problems of the 1998 Oldsmobile 88

The contact owns a 1998 Oldsmobile 88. When the vehicle was started, smoke appeared without warning. The contact observed oil on the manifold. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The VIN was unknown. The failure mileage was approximately 120,000.

Engine hydro locked when a crack in the plastic intake manifold allowed coolant to be sucked into the engine cylinders, causing the engine to lock up while my wife was driving it. Fortunately, no accident occurred, but this seems to be a very common problem due to what seems to be a design flaw by gm. We had to have the engine replaced, and the intake manifold, at a cost of $5,400. 00. We heard that there was a class action lawsuit because of this problem, but people were just afforded a short time to act on it, and we were not even notified. Is there another suit that we can be a part of? we should not have had to replace an engine with just 44,000 miles on it.

While driving,\ the check engine light flashed on the dashboard and remained on. Then, the vehicle stalled. Driver was unable to restart vehicle. Noticed that coolant leaked from underneath the vehicle. It was towed to the dealer, and mechanic determined that the intake manifold needed replacement. Driver informed the mechanic that this problem occurred more than once ,and has not been resolved.

Consumer received a recall letter regarding the fuel pressure regulator. Prior to receiving the recall letter consumer's vehicle experienced failure of the engine intake manifold. Consumer is requesting reimbursement of expenses incurred to repair vehicle prior to receiving recall notification letter.

I purchased a 1998 Oldsmobile 88 in March of 2003, I put new wiring on the vehicle approximately in December after I had the vehicle checked because the check-engine light was on. The check-engine light started coming on again and the car was using all the water about every 10 miles, I took the car to a repair shop where they told me that there was a problem with the intake manifold. After leaving the repair shop, I stopped by a store and was inside about five minutes and the car wouldn't start right away, I had to try starting numerous times before it would start. On my way back home the car slowed to about 40 mph and wouldn't go any faster, even with the gas to the floor; it would only get slower. After getting back home, the car wouldn't crank back up at all; it wouldn't even turn over. I bought the car back home that same day and checked the internet for any recalls on the vehicle and noticed that there was a recall in February 2004.

1) Aug. 2000 generator failure 2) Aug. 2002 both rear wheel cylinders replaced 3) oct. 2003 coolant leaking : replaced leaking water pump. Intake manifold also leaking but not replaced at this time due to cost. 3. 8l v6.

Gm has a plastic plenum/manifold on their cars that become defective after 60 to 70 thousand miles. Due to the heat that the manifold is exposed to, the part will than leak. When this part was made from aluminum it would not cause these problems. I have replace this part 2 times in 2 1/2 years. Gm will not help with the bills because I have over a hundred thousand miles. But the part only has 65 thousand miles on it. I have gone to 2 auto repair shops and all I tell them is I am losing coolant and they know what the problem is. They said they replace these often. They replace these so often that now there is a after market that this part can be purchased from. My husband is a mechanic and knows what to look for on our regular maintenance, and that is how this was found. If people don't catch this coolant loss in time they could blow their engine. If people are not aware of this problem how can they watch for it?.

Leaking coolant from water pump and from intake manifold.

The consumer noticed the intake manifold had a crack, which caused fluids to leak out.

Car was running rough, esp. On starting. Made appointment with dealer who couldn't look at it for a week. We realized it was losing coolant, but there was no apparent leakage under the car or hood, etc. Filled with coolant, drove approx. 4 miles then engine light came on and stayed on. Checked oil and it was over "full". Called the dealer back with the new symptoms and was told it was a common problem with this type of car to have coolant leak into the oil (then into engine) and it probably needed manifold work $600. --$700. Had car towed to dealer where they found the manifold did need to be replaced. In researching, we have found that this is a common problem in 88's and sometime results in engine fires. We are wondering why there hasn't been a recall and why would the manufacturer use plastic in engine parts!?.

Fractured plastic (!) intake manifold (upper plenum) resulting in loss of coolant over the course of about four weeks until the problem was finally diagnosed. Had to have this problem analyzed and eventually remedied at a cost of around $700. 00 total. Why on earth is this crucial component plastic?.

When starting the vehicle, the intake manifold had blewout and caused the vehicle to be non drivable. The dealer was notified. The "explosion" woke up the neighbors. There was smoke but no fire. Bby.

Car has 55,000 mi on it, and the plastic intake manifold resting on top of the engine cracked, leaking all coolant into the engine. Vehicle was shutdown as soon as the temperature climbed to about 250 f. Problem was fixed by replacing the plastic intake manifold, and no other damage to the vehicle resulted.

The intake manifold on mt 1998 Oldsmobile 88 failed recently. The plastic on aluminum intake manifold is very susceptible to corrosion. Apparently mine failed and all the water drained from the engine. The repair bill to get the car running again was $1838. I am told by several people that this is a common problem on gm cars. Because of the common occurance of this problem, I would like to think that a recall is in order.

The manifold on the consumers vehicle was replaced at his expense one year ago and now there is a recall on the fuel pressure regulator, which the consumer believed somehow affected the manifold. Gm stated the defect did not affect his vehicle. After the engine was warmed and started, it would take a couple of tries and then the vehicle would surge when starting. The fuel pressure was leaking. The vehicle continued to lose coolant.

The intake manifold cracked which resulted in coolant leaking into the engine and caused the engine to seize. The problem caused extensive damage to engine, starter and flywheel.

The intake manifold degraded, which caused coolant to leak onto the engine, which resulted in the connecting rod breaking and going through the engine wall. The dealership had to replace the engine. Ts scc.

Engine began to run very rough and check engine light began to flash. Pulled car off roadway. Gasket had failed sending coolant into the engine, damaging the manifolds.

Consumer states vehicle has a plastic intake manifold assembly. The component melted causing coolant to get into engine. Mr.

The vehicle would not start because the intake manifold leaked antifreeze into the cylinder.

While driving less than 35 mph, the consumer noticed the vehicle did not gain any speed, followed by the engine losing power. The vehicle was towed to a technician who then informed the consumer that the manifold needed to be replaced. Please provide details.

While driving there was an explosion in the engine compartment which blew the intake manifold apart. Please provide any additional information.

White smoke expelled from the exhaust pipe and the engine stalled. It was discovered the sleeve which sealed the exhaust gas as it entered the intake manifold leaked. . . .
