RE: the pics I posted
Yes, that's a 99 3.4 motor in the pics. Actually both parts are for a 3.4. The wire in the first set can be seen in the second set. The first pics show a seal replacement from the outside (aka easy job) the second is the actual solenoid (seen in first pics from outside) much more involved and much much less likely to be the actual cause of the leak
