Manifold leak developed around 55000 miles, resulting in loss of coolant, and $1000 repair, of an apparently common problem with gm 3. 1 liter v6 engines. Mine is a 1999 Chevrolet Lumina.

I purchased a 2001 Chevrolet Lumina on March 15,2002. Three to six months after purchasing this vehicle my wife and daughter began to complain of headaches, dizziness, stomach aches, nausea, and extreme fatigue. We didn't know what was causing these symptoms. We took our daughter to the doctor several times and could not find any reason to explain symptoms. Eight months after this purchase my daughter developed a respiratory illness known as reactive airways disease. We are currently treating her for this illness. My wife researched the symptoms and came up with the conclusion of carbon monoxide poisoning. We have electric heat in our home. The only place they could have been exposed to carbon monoxide was in the vehicle. I returned the car to the dealer one year after purchase. We were told that there was a leak in the trunk. They hammered the trunk gasket and said the problem was fixed. The symptoms were still present. We purchased a household carbon monoxide detector and placed it inside the car. The detector went off twice proving there was CO in the cab of the car. The dealer replied with "if we cannot see it we cannot fix it. " I have contacted gm customer service and we are currently working on finding a solution. I have personally rented a lel handheld monetor manufactured by biosystems. Within 20 to 25 minutes of being in the passenger compartment of the vehicle I receive readings lel 6, CO 6, 5, 3, 6 constantly fluctuating yet always present. 3 to 5. Are these safe readings? what can these gasses do to my family? no dealer in our area seem to have a tester to test inside the vehicle. Diagnostic tests all come up negetive for exhaust system leaks. Could this have caused my daughters respirdatory condition? what should my next step be? am I the only person who has contact you for this type of problem?.

"gm should recall faulty intake manifold gasket installed in their vehicles". As of April 10, 2002, there is a nationwide backorder of the intake manifold gasket. At this time, is it not even known when the part will become available. Being aware of this proves there is a serious problem to be addressed. Because of apparent poor engineering, gm can not manufacture replacements fast enough for all the vehicles in which they are needed. Intake manifold leaks can lead to any number of very serious, and expensive, problems. While the part itself isn't costly, the labor to repair it is very intensive, and has been quoted around $800 usd (give or take a couple hundred depending on the vehicle). This is in addition to any other costly problem(s) the intake manifold gasket leak may have produced.

There is a bad smell in the vehicle and, consumer thinks that it is a health hazard. Contacted dealer, and took the vehicle in for service. They can't find the problem.
