1996 Pontiac Transport van with leaking intake manifold gaskets. Consumer states that the internal manifold leaked filling the oil pan up with water which in turn froze the main bearings to the crankshaft, causing the vehicle to lock up at 50 mph. He sent in previous letter about the same problem on another vehicle. The consumer noticed a smell of anti-freeze, but could not locate the problem, because it was internal not external.

Failure of the intake manifold gasket.

After the 2nd valve spring broke, I was told that the valves were seizing up and a new engine would be required. All of this was caused by the bad designed manifold gasket that caused coolant to go into the oil. After spending over $1,000 since 4-29-03, I finally had to trade in for another vehicle. I didn't have between $4,000 and $5,000 for a new engine, which on a '96 model would not have been worth it. I could have gotten a used engine, but all of them have the same manifold gasket and this would have cost aproximately $2,000. I've had nothing but problems with this van. General Motors should have taken care of this as a recall, but I guess it was too expensive for them too.
