Payne, Narrow down what's going on. Yes, Replace the cooper washers with new ones every time. Also, New injectors can also be faulty. The fuel distributor may be delivering more fuel to that cylinder than other even thought that's unlikely. Swap out the injector with a known good one in the car see if that new swap out leaks. If it does also, then there may be a blockage in the injector seat or a shim problem in the fuel distributor. John hervey http://www.specialtauto.com/ Call me if I can help.
