This Oldsmobile Silhouette has had so many many problems over the past 3.5 years, I have finally had enough. I noticed an occasional engine "whine" or rattle while driving, but it was so sporadic I wasn't sure if it was really happening. Then last week it seemed as though the heat wasn't working well in the van...the temperature wasn't below freezing, but the heat just wasn't warming up sufficiently. I mentioned this to my husband and he noticed it the next time he put the heat on, too. At the same time he noticed that the engine termperature was fluctuating as he drove and stopped. He thought at that point that it might be the water pump and immediately (yesterday) took the van to a Firestone center for repair. Turns out the water pump was fine, but the mechanic diagnosed the problem as the lower intake manifold and said it would be a very pricey repair and that there was probably engine damage because of the failure of the lower intake manifold. The mechanic said that it was an inherant problem with this engine. We had no work done at that point. I contacted my local GM dealer and was told that the problem was not widespread and olds/GM was not doing anything to help the consumer with this repair. The van is now sitting in the driveway, unable to be used because of this mechanical problem.

I have leaky intake valve gaskets on a 2001 Oldsmobile Silhouette van which has ruined the ehgine. GM will not do anything. I have many friends who have had the same problem. There are thousands on the internet who report the same problem in the 3.4 V6 GM engine.

The consumer is experiencing a problem with the vehicle overheating. The vehicle was taken to the dealer and a local repair shop and both confirmed that the problem is a leak in the intake manifold gasket.
