Manifold/header/muffler/tail Pipe problems of the 1999 Chevrolet Venture - part 1

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 responsibilty for this design flaw in their engine. The government needs to step in and order a recall.

Ball bearing on vehicle replaced 2007, now 2008 won't pass inspection must be replaced again, plus the engine manifold.

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.

1999 Chevrolet Venture developed problems with the thermostat, and the intake manifolds. The thermostat was replaced, however that did not resolve the problem.

I have had numerous problems with my 1999 Chevrolet Venture which my husband purchased new for me in December 1998. Last year I experienced problems with the engine light staying on, coolant level constantly dropping no matter how often we added dex cool, and then in the spring I had to have the intake manifold replaced due to engine oil in the coolant. He told me he has had several customers with chevy Venture and olds silhouettes with the same problem. Just a couple of months after this repair which cost me over $1,000. 00 my car suddenly stalled in heavy traffic on route 22 on my way to work. I managed to get it to the shoulder before it stopped rolling despite losing power and called my mechanic. He towed me to his shop and has informed me that my camshaft is broken and he has never heard of anything like it before! well, after finding this site while researching what to do about this problem, I found this site and was shocked to see all the same complaints and since at least 2001 Chevrolet has known about these problems and didn't care about their customers enough to warn them or offer to replace the source of the problem before we had major engine damage like mine. I am lucky I was not killed on the highway by a truck rear ending me or something! I am a single mom with 4 kids and I still owe my mechanic over $800. 00 for my last repairs and now this! no way can I afford to replace the engine! besides, another Venture engine would just have more problems! and now I'm reading about other problems like air bags not working and windows exploding and transmission failures, tail lights and electrical problems! these cars are death traps! and most people who purchase Mini vans have young children! gm should be ashamed!.

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.

Vehicle was losing coolant due to defective intake manifold, but there was no leak. All of the repair shops and dealership claimed this intake problem was common with this engine. It took dealership two months to repair vehicle.

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.

I own a 1999 chevy Venture which has been driven 26,000 miles. I took my vehicle in foran oil change and on inspection the dealer found coolant leaking from all four corners of the lower intake manifold gasket. They replaced the lower intake manifold gaket and related gaskets at a cost to me of $753. 88. The service supervisor informed me that there was a defect in the gaskets and that they have been seeing and fixing this problem on vehicles with this particular motor. He informed us that if we did not get our vechicle repaired that the engine might seize up. I called the corporate office for Chevrolet and they stated that there was no recall on the faulty gaskets at this time. Iak.

My 1999 Chevrolet Venture has 59,800 miles. While driving on the highway I noticed the "coolant level low" warning light on; the coolant reservoir was nearly empty but there were no visible leaks. The mechanic told me that the intake manifold was leaking. The service shop replaced worn gaskets. This is an expensive repair which should not be necessary at 60,000 miles. I have a friend who owns a 1999 Venture which has had the same problem, and he told me of two others in his circle of friends.

I bought a used 1999 Chevrolet Venture with 54,500 miles on it. 7 months and 32,000 miles later, the van is at my local Chevrolet dealer with $1,650 $2,200 of engine damage, due to an intake manifold gasket failure. The vans 3. 4l engine was well-maintained, with frequent oil changes and inspections. The only warning sign that I got was that the coolant level had to be topped off about once a month. A mechanic said that the coolant loss was due to evaporation. My mechanic offered to replace the engine with a used one for $2,200. He would put a new intake manifold gasket on the replacement engine, so I would be less likely to run into the same problem again. I learned of gm technical service bulletin #03-06-01-010, with subsequent revisions appended a and b, which describes a repair procedure for coolant leaks on 3. 1l and 3. 4l engines. The repair procedure is install a new design intake manifold gasket. The material used in the gasket has been changed in order to improve the sealing qualities of the gasket. When replacing the gasket, the intake manifold bolts must also be replaced and torqued to a revised specification. The new bolts will come with a pre-applied threadlocker on them. my son called Chevrolet customer assistance and spoke with john brooks, who told him that I would have to have my van evaluated by the service department of a Chevrolet dealer before he could offer any assistance. He gave me the following service number with which I could reference the call: 1-201938-040. The intake manifold leak was confirmed at the local Chevrolet dealer. The service manager estimated that the engine could be repaired for about $1,650, including parts and labor, but that he couldnt confirm the extent of the damage without getting into the engine. getting into the engine would cost $500, after which there would be no going back. he said there would be no assistance from Chevrolet, as I hadn't bought or had my vehicle serviced there.

I took my van in for an oil change and they told me I had anti-freeze in my oil. Therefore I needed to have the intake gasket replaced, otherwise the engine would fail. This job cost me $777. 00 to have corrected. I had owned the van for less than one year when these problems occurred. The van had 55,133 miles on it at the time. The funny thing is a few days after I purchased my van my mom purchased one also. About 2 months after she had hers the same problem happened and she had to have her intake gasket replaced also. Apparently there is a problem with these gaskets and gm should replace them. Or at least reimburse us for this money we had to fork out for a problem that is apparently a little more than a coincidence.

Dealer diagnosed coolant leaked into engine mixing with oil (from intake manifold gasket) causing top end engine damage (hydralic valve lifters had to be replaced and intake manifold gasket) . Mechanic who worked on my van said it was very common problem the 3. 4l v6. Had vehicle for little over 3 1/2 years with 36227 miles (cost $862) when problem occurred.

The engine blew with no indication of major trouble while driving at 70 mph on interstate 5 at around 6pm. Major safety concerns with no power to the accessories, having to coast off the freeway exit and having to push the van to safety. Dealer says that it may be the cam shaft.

My 1999 chev Venture van required the replacement of the intake manifold gasket at about 65,500 miles. Service department stated that this was due to a bad batch of manifold gaskets and that GMC was now getting gaskets from another supplier. This appears to be a major problem within gm products; however, no recall has been issued; nor was there any offer of a discount or refund from the dealer for this apparent defect. This could be considered a safety problem as the engine could get water in it and freeze up. If this happens during the winter, on a backroad in minnesota when the temperature may be well below zero, serious consequences could follow. I see a pending law suit coming.

Noticed that coolant level was slowly going down and needed to be refilled. Took van in for coolant flush. Dealer would not do flush because intake manifold gasket was leaking coolant.

He has encountered this problem many times before with chevy Ventures. Luckily, coolant had not yet leaked into engine oil.
