I replaced all freeze plugs about 3-4 years ago on my 56 235 and everything has been fine since then. Now all the sudden I have a small coolant leak from the rear of the engine inside the bell housing. I assume the rear plug is leaking again but obviously it is not rusted through yet like the old one. A bad back now prevents me from getting everything out of the way to repair it a second time. What is the best and safest sealer to put in the system to take care of a small leak? I see posts on Bars Leaks but they make a couple different types. Or would it be better just to put up with it unless it gets much worse? ( about a teaspoon size puddle on the floor after a drive.}
Thanks for your advise
