Paul,
I would have to say there was some sort of a defect. A short perhaps.
The oil is used as a cooling agent. I hope they didnt use PCBs. One
thing you might check is your point settings. A coil will heat up if
those points dont open as much as they should. Remember points closed
means 12V to the coil! Make sure the distributor cam is well
lub-der-cated. In my 3, I mounted the coil on the inside of the wheel
well. It seems to get a bit more air flow. I know it is not stock, but
my car is never entered in shows so I dont really care. I also use the
sport coil and have never had a failure.
