My 1998 old Silhouette had intake manifold gasket replaced at 69, 000 miles and then 8 months at 73 000 mile my cam broke in half while I was driving at 25 to 30 mph unknown why or how much more damage is done at this time. Investigator is coming out to check what had happen .
We purchased a van in good working order in 04/2006. It was used previously by one owner since being purchased new. In November 2007- it began overheating and losing coolant. The diagnosis is now replacement of head gasket and possible intake manifold gasket. This is a very common problem with this particular engine. Gm has refused to help their consumers in any way if there is no warranty. As with all problems these could fail due to normal wear and tear, mileage, and or age. I do not believe this to be the case in numerous complaints including my own!.
: the contact stated the low coolant light illuminated and the vehicle was not warming up properly. The dealership determined the antifreeze was leaking into the oil. The manifold gasket was replaced. When the problem returned the manifold gasket was replaced a second time. Two other members of contact's family had the same things go wrong with their vehicles. The dealer won't help the contact to defray the expenses because he used an independent mechanic that once worked at the dealership. There weren't too many dealerships in the contact's area. Also, the contact knew many people who had similar engine problems.
Contact took vehicle to a service dealer for routine maintenance and they replaced the lower intake manifold to stop the coolant leak. The consumer stated vehicle was still leaking gasoline and coolant. The consumer did not want to have this problem repaired at the time of the routine visit. The consumer stated the service dealer had to keep the vehicle for about a month.
Began to see coolant pooling on the intake manifold assembly, took the vehicle in to find that the intake manifold gasket needed to be replaced. Should have been a warranty item. Did not damage engine, I was lucky and spotted the situation early.
The consumer stated the intake manifold gasket failed without warning. As a result the transmission fluid and oil began to mix together, which caused the engine to stall. Please provide additional information.
The following letter (combined message forum posting & letter to gm of mine) represents the main points in my complaint involving an intake gasket manifold leak in our 1998 Oldsmobile Silhouette which we've since repaired for approximately $900. 00: after recently writing a lengthy complaint letter to Oldsmobile customer service (explaining how I was trying a gm product for the first time after being dissatisfied with Chrysler products for the past 10 years) and after 2 weeks of phone tag with 2 gm customer service reps I was finally told that because I wasn't the original owner, bought it with relatively high mileage (50k mi) and didn't have an extended warranty gm is not going to assist with the repair of my intake manifold gasket problem. I summarized by saying, "so, you're saying that gm doesn't care what 2nd owners of gm vehicles think about gm? you don't care that I won't buy another gm product?" the rep. Responded "that's your choice. " he went on to say "we don't know how the previous owner maintained the vehicle. . . . " and I responded saying "there are TSB's out there on this problem, over 1500 people who've signed an online petition and gm dealer service techs who immediately point out the problem to owners who go in for totally unrelated service; you can't tell me that gm doesn't know this is a product defect. " he didn't respond. My vehicle is now consuming about 16 oz. Of coolant every 150 miles driven. The rep. Said I shouldn't be driving it at all; easy to say if you could afford to go out and replace it or repair it; not a very good option for our family now. An extensive web search on â??olds Silhouette and intake manifold leakâ?? has produced many stories of exactly the same problem with other owners of this vehicle in the same year. I request that this problem be repaired free of charge as soon as possible to avoid further damage to engine components.

I have just found out that my olds Silhouette has a coolant leak in the intake manifold withh only 50000 miles on the odometer. To my discuss I was informed that this is a very common and "predictable" failer. I hope that it has not caused any further damage to my engine. It would have been in the least a reasonable action on behalf of gm to give owners of their vehicles a heads up on this all to common defect.
