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.

There is no water behind the timing gear.  i had the same problem. Old gaskets come off hard and very small remnants can remain. I took a quality putty knife, put a sharp edge on it and was amazed at how much of the old gasket remained. Bolt(s) that reach the water jacket MUST have a sealer. The new gasket and sealer must get warm in order to seal. I rotate tightened the bolts. The started the engine and let it get warm! With a good air nozzle I watched for leaks, the small incfements tighter, til it was all dry. Its a bit tricky. CREEP up on tight, you do NOT want to twist off a bolt.

 

Good luck, hope this helps.
