I am trying to get my Flattie running again, it has sat too many years. I have replaced the water pump and flushed the block and radiator. Put on new hoses and added coolant. Went to watch the F-1 race came back and all the coolant was on the floor. It appears that the leak is coming from the timing cover. Is there a freeze plug behind the timing cover? I rebuilt the engine in the mid 60's and I can't seem to find out if there is a plug there or not. Engine is for a P-6.
