Manifold intake gasket had to be replaced twice now on my 1998 Chevrolet Venture (2003 and 2005). Also the rack and pinion needs to be replaced for turning left.

Vehicle taken in for routine oil change at 39000 miles. Mechanic informed us that there was a manifold intake leak that would cost $600+ to fix.I did not do the repair, but have since been informed that there is damage to the engine and that not repairing could cause sudden engine failure. Something known and common like this is shameful for a car 3000 miles out of warranty. I suspect the problem was present at the oil change prior to 36K.

Engine stalling and under performing due to manifold gasket leaking coolant into engine. My wife was entering a main road from our sub-division driving our Chevrolet Venture '98 when the engine started running roughly and sputtering. This could have been fatal with the oncoming traffic. This problem was due to a leak of coolant I believe into the engine. It seems GM is aware of the problem but has not notified owners of the vans. At the least they should be making consumers aware of the problem and the fact that engine failure could occur during critical times.

Extreme leak in the intake manifold gasket, leading to possible engine damage due to coolant destroying aluminum components of internal engine parts. The following was done to prevent immediate engine failure: Replace intake manifold gasket and thoroughly clean inside engine ($771), replace oil pressure switch ($86), full coolant flush ($105), oil/filter change ($15), and replace coolant sensor ($85). Consistant with historical failure of all similar makes/models. Customer pays for GM's poor product.

Driving down the highway my van over heated and stalled with no prior warning. I had to replace my head gaskets, lower intake, all my spark plugs and spark plug wires. I had no leaks that I was aware of. Nothing on the gorund to even suspect a leak. Apparently I was leaking so bad internally that 2 of my spark plugs crapped out and my van refused to run. From what I read this is a fairly common complaint among Venture owners. I really love my van but this flaw will prevent me from buying another one, which I fully intended on doing in a few year. Sorry GM but I'll go with a Honda next time.

I recently purchased a used Chevrolet Venture minivan. After approximately 6,000 miles driving, the intake manifold gasket failed and I now have coolant in the vehicle oil. This is an expensive repair and after considerable internet investigation, I found literally hundred of other owners with the same complaint. It appear that GM has known about this problem for some time and refuses to correct the problem. So far, I have not had the vehicle repaired because of cost, but I think that GM should be responsible to Venture owners to repair this defect cost free to the owner.

While the consumer was changing the oil noticed engine coolant intake manifold head gasket developed a crack.

- Orland Park, IL, USA

Rear window on vehicle blew out. In 2001 the rear window had to be replaced because it had blown out. In 2003, the same window had blown out again which was the original from GM. There was no seal around the original window. The lower intake manifold seal had to be replaced by GM in which they covered half the cost. There were other Chevrolet's with the same problem. (the cracked sealed leaked coolant into the engine) the consumer felt that GM should reimburse the insurance company.

1998 Chevrolet Venture van 3400 dex coolant engine, intake manifold gaskit & head gasket left us stranded on the side of the freeway with 3 children in busy July 4th traffic, had to be towed home and call for someone to pick my self and children up while my husband waited for a tow truck. From the research we have done this is a common problem with this engine that Chevy will not publicaly admit too even though they have redesigned the intake manifold system for the new vehicles.
