Hi, I was changing my oil one day, and stripped the hole in the oil pan. I took it to a shop, and they put a "rubber" plug in it, since the original bolt would no longer fit. I took my car out of town, and while I was parked, the plug cracked, and all the oil leaked out. I took it to a shop close by, and they put another rubber plug in the pan. I just needed something to get home with. The first rubber plug lasted about a month. What do you guys think of these rubber plugs? Right now, I don't trust them. I want to have a new oil pan installed, with a metal plug. How much do these things cost, to have them installed? Can I purchase a cast iron pan, instead of the thin aluminum pan that came on the Saturn? The hole stripped so easily. Thanks in advance! Scott
