When I pulled the oil drain plug out it turned out to not be a drain plug at all. It was a standard thread sparkplug thread saver plugged with a blot that had FIAT stamped on the head. someone had tried to JB Weld this mess in place so there was a huge blob of stuff where the oil plug should tighten up against the oil pan. Got it all cleaned up and a new drain plug of the proper size in place and all is good. Also, a few months ago I posted in reference to only one cooling fan working. I finally tracked it down to one the wires that goes into the fan fail socket. It was installed in the slot that should be the ground tab. I relocated one leg of the fan fail bypass and solved the issue.
