Hey there. So first time on here. I own a 2008 Smart fortwo passion gasoline and the last place that changed my oil stripped the oil pan. I am either going to put ahelocoil insert in or use one of those eco plugs as a temporary solution. The oil plug is in with the new oil change finger tight and was wondering if anyone knew what the thread size is so i will have the parts ready when i fix it?
