Recently rebuilt engine in a 2000 Ford Mustang with 3.8 V-6. The engine was machined and reassembled with new pistons, rings, ect. #3 cylinder si leaking oil so bad as to foul the plug where it will not fire. #6 plug is dirty on inspection, but is still firing. Is it possible that I have a bad valve seal even though they were all replaced, or maybe the rings did not seat on those two cylinders? It puts out a little blue smoke and also has a strong oil smell when it is first started. Thanks for any advice you can give.
