Well today, a buddy of mine came over and we installed some lowering springs, yada yada. Anywayz, he then took the car for a test drive, came back and it was sputtering (sp?) Anywayz, i checked his plugs. The plugs from cylinder 1, 2, and 3 were fine, but cylinder 4's plug was DRIPPING with oil?? What do you guys think blew out?? The piston's Oil ring? or the head gasket?? Thanks you guys
