Hi all, Does anyone know what socket is the trainsmission flud drain plug is suppose to be? I.e. size. It looks like a square socket but I'm not sure of the size. I hate to get a wrong sized socket and go back for another... Also, does anyone know why white smoke is coming out of the exhaust? My guess is that timing belt might be bad or off. I once messed up a civic's timing belt and it did the same thing. The engine came weaker and there was lot of white smoke came out of the exhaust. Any advice would be appreciated.
