Unable to find a OEM GM Part - Catalytic Converter. I have had it replaced with a Walker & Magnaflow but the converter keeps going bad after about 1 or 2 months. Not sure if there is something else wrong with my van or if the mechanic is doing something wrong. I have not found anyone else having this problem and I know there are alot of 1998 ventures out there. Help. Is there anywhere that stocks parts which GM no longer makes.

walker cats do not have enough precious metals in the converter to keep the light out.
ask for a super cat made by bosal. we use them with great sucess. they are available at parts houses.

Do you think this is better than the magnaflow? I was told that that one was the best. Also, my coolant light has just come on. I checked with Dobb's and they said all levels were good and that it probably was a stuck sensor. In 2003, my lower intake was leaking coolant and had it repaired and replaced as well as gaskets. I keep reading about the venture having this problem with their gaskets and that leaking coolant can hurt the cat. The light just recently went on and I have been having cat problems since 12/2007. The cat has been warranted but the labor I have paid for twice. What do you think about a possible coolant leak or have you had problems like this with other cats until you used the supercat.
Just looked into the Bosal. I do not believe that they make a Super Cat for the 1998 Venture
