Last winter on my 83 when I was running the block heater I noticed a little drip of coolant, yet it won't leak just driving around. What is the deal with this? I also only use mine when below 20*F. Anyone have a heavy duty timmer? I'm thinking of getting something like that this year. Another nice thing for the motor in the winter is a semi or full synthetic oil, the difference is unbelievable in speed of turning over. Btw, I just stopped in to wally world today and picked up some Mobil 1 15w50 supersyn, 5qt jug for $18.88, it has a pour point of -49*F.
