I bought this Accel brand coil online about a year ago. I doubt i still have the email receipt. Or if it would do me any good, after this long. Though i still had the box. I painted it black, to look stock, and mounted it horizontally in the stock location. Today, i happened to notice an oil puddle on my intake. This thing is leaking, and i haven't even fired the motor up yet. Is this just luck of the draw, for crap made in china, or is this common for this particular coil ?
