Carl and Jon,
Thanks for the response. I really don't want to change the one behind the bell housing, and I do not use stop leak. This engine was rebuilt 14 yrs ago and won't be done again. I will probably go over to the DARK SIDE" small block" before another rebuild. I have used the expandable rubber plugs before, and it doesn't ever get that cold here in Metairie. So I guess I will think about it for a day. It's a lot of work to get to the one behind the bell housing.
