Wondering if I can do my rod bearings myself? I just need a torque wrench, oil pan gasket, new bolts?? bearings from GM or ?? This & lots of patience I figure. Do i need to plasti-guage them? My mechanic friend said about $200 to do it. Is this a safer way to go? Its not the money, just getting itchy to do something to help survive winter! Car does like the cooler temps now, but the snow is coming eventually! Thanks!
