I'm relatively new to the svt focus scene and just rebuilt the head on my 2003. After starting it for the first time and driving it around a bit I parked it over night. The next day I saw a 6" diameter puddle of new oil. The location I found the center of this puddle is about 1" behind the radiator, almost straight below the header. I've checked all around the oil pan, head gasket, and valve cover gasket for a leak and found nothing. I also looked under the car and found no visible area leaking. Is there any known area where this might be coming from other than where I have check? Any tips are appreciated. Thanks!
