[QUOTE=Mark Nixon;2705305]I don't know the name, but I was told there is a product that will stop leaks from porous castings and minor cracks.
You might look into it some.
Another option would be a bottom fill with block concrete.
Seen a couple 53 block leaks cured that way.
Or, there's still this engine in my garage.
I'm supposed to get with the machine shop to see how they want to handle it, this week. I'll let him know after that what I decide to do about the motor in the garage.
There is an old mechanic next to us at work who can fix anything and keep it running with what ever he can cobble together. Told me he has used some sort of product for sealing floors that has liquid glass in it. Might be worth a try.
