On september 19,2003, my 1998 pontiac bonneville with 3800 v6 overheated(check engine light and high temp on gauges), would not restart and would not turn over by starter motor. Had to tow into shop and had cooling system checked. Pressure leaks were detected. The shop mechanic diagnosed that the upper plenum for the intake manifold, which is made of plastic, had become warped where the egr valve connects to the engine block. This allowed antifreeze to fill up the engine cylinders. The small repair shop where my car was repaired stated that they had replaced many of this particular upper intake plenum for this particular engine. The tow truck driver told me what the problem was even before I told him the entire problem.

This car has had very good care/maintenance, has not been driven hard, and has only 67,000 miles on it. While driving down a city street, approximately 35 MPH, the car began to sputter. I pulled in to a parking lot and shut the car off so that I could look at the spark plug wires. I had a spark plug wire loose when this happened once before. I had no over temp, I had normal oil pressure and there was no check engine light illuminated. I did not find a noticeable problem, but I could not get the engine to start again. I had it towed home. I changed the battery, the starter, and finally checked to see if the crankshaft would turn, which it wouldn't. I removed the spark plugs and tried it again. I got antifreeze from four of the cylinders! This was determined to be because of a failed intake manifold gasket.

On july 1, 1998 pontiac bonneville with 3800 v6 overheated. Took it into shop and had cooling system checked. No pressure leaks were detected. When I left the shop, engine began missing and check engine light came on. Engine smoothed out, but took back to shop and they put on machine. Cylinders 1 and 6 had been misfiring, but seemed to be running fine. The next day on way to work, the engine began missing badly again and temperature gauge went up to about 240. After work, engine would not turn over at all. After having car towed back to shop, I learned that the upper plenum for the intake manifold,which is made of plastic, had become warped where the egr valve connects to the engine block. This allowed antifreeze to fill up the engine cylinders.

I own a 1998 pontiac bonneville with 87,000 miles and out of warranty. Late one evening my car suddenly let out a cloud white smoke and stopped in traffic. I assumed that when the engine light came on and the manual suggested "a tank of bad gas" or similar problems that the problem was not serious. After having my car towed to my dealer, I was very surprised when my dealer informed me that the intake manifold had cracked and coolant had infiltrated my cylinders. This "minor" repair ended up costing $1836 after replacing the manifold, gaskets, hoses, and thermostat. I do not have much trust in my vehicle nor the automobile manufacturer who knows that this is a problem with my year and model of car and does nothing to warn owners of this problem. I feel that I should be compensated for the parts and labor to replace a manufacturer mistake.
