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

If so, no rust advancement and leak sealer may help you keep driving. If steel was used, could be rust, but 3-4 years? antifreeze and water? May still be the plug seal. Are you sure it's the plug? Not an emergency if you keep watch on water level. Hope you get to feeling better. Getting at that plug may be a big job.

I can't say for sure its the plug since you can't see it to check but the block above the bell housing is dry and nothing on the sides of the block. And yes it is a big job and not so much fun the second time!
