Losing oil on 2000 Chevrolet Venture minivan and went for service. They found that the intake manifold gaskets leaking coolant and oil. They explained this would have caused critical engine issue if left. Have read many other complaints with this exact problem and also service notes from GM on this topic. The van has only 49000 miles. I paid over $950 to fix a GM defect.

Labor day 2004 traveling through rocky mountain national park, engine coolant overheated. Had replaced coolant 2 months previous. Temperature gauge now always shows cool. Today had routine oil change and shop advised intake manifold gasket leaking and needing replaced. Upon researching the problem, discovered it is extremely common on Chevrolet 3.4L engine and often leads to cam shaft and even total engine failure and replacement. GM currently ignoring condition.

I'm writing you this letter since GM has refused to acknowledge they have a factory defect in the intake manifold gasket and bolts of may of their GM vehicles.: to include my 2000 chev Venture. Recently while on a long trip over the holidays I noticed the low coolant light had illuminated and discovered our coolant was leaking. I took it to the shop today and it cost me $895 for the repair...not bad compared to some but still a cost one wouldn't expect to pay on a car only 3.5 years old and 70K miles. My wife and I have done some extensive research and found this seems to be a significant problem with GM cars but yet there is no recall for the problem. The result of these gasket failures is clearly a design flaw and we've N documentation where your company is paying for other models manifold repair cost. Looking over this site and others dedicated to this problem I've found numerous other stories similar and many even worse. I find it hard to believe GM is not stepping up to fix the cost of these repairs....they will lose my business.

61,000 losing collant due to intake gasket leaking. I have read several complaints of this problem and nothing is being done. Why not?

I took our 2000 Chevrolet Venture minivan in for service and they found that the intake manifold gasket was failing. This was causing anti freeze to leak into the engine which eventually would have caused the engine to need to be rebuilt. Come to find out the next day there is a GM tsb 03-06-01-010 on this exact problem. Our van has only 45,000 miles on it and I do not believe this should fail especially with so few miles on it.

Since purchasing my 2000 Chevrolet Venture minivan in October, 2000, I have been experiencing loss of coolant since December, 2003. At this time the car had just over 75,000 miles on it. None the less I had kept scheduled maintenance on the van. On every scheduled maintenance Chevrolet prescribes ( from 7,500 miles to 90,000+) "check for oil and coolant leaks" is listed. I find it difficult to believe that at no time during any of these check up the mechanic at the dealer did not notice a coolant leak until 80,000+ miles later and after my warranty has expired. Now, I have been advised that the intake manifold is leaking and the repairs are going to cost ~$900. I contacted GM customer service, and was given several excuses to justify Chevrolet's action, (or lack therof), from "that's a lot of miles. And any part is going to wear out after a while" to "if there needed to be a recall it would have to be demanded by the government". hogwash!!! based on the number of complaints I have read this evening, and even the verbal confirmation from my service advisor that "we're seeing a lot of these", Chevrolet does not have to wait for the government to say, we have a problem and we need to fix it.

Manifold gasket allowing anti-freeze to leak.

- Windsor, CT, USA

The manifold gasket has been leaking intermittently since the vehicle was new. We have returned it to the dealer for service and we were told that no problem existed. I have a friend who has had the same problem with his 2000 montano and ending up replacing the manifold gasket at great expense. My Venture has 55,000 miles on it and this is far to soon in it's life for major repairs like this.

Chevrolet Venture with 40,000 miles develops coolant leak- dealer says it is intake manifold gasket and it would cost $900 + to repair. After much complaining to GM, they agreed to "extend" the warranty and repair the car for a $100 copay. However, this is a widespread problem and it needs to be recalled. Whole websites are dedicated to complaining about Chevy intake gaskets. The car could have a catstrophic engine failure, over heat and have a fire. It is a very serious problem and GM plans to continue to ignore it. I got lucky, but many people pay for repair which should never happen on an engine with 40,000 miles. GM should be ashamed.
