Has anyone used the product Steel Seal in the coolant to fix potential gasket problems? I have a Universal MX 25.

I can’t say that I have...I am not sure I would. But if you do, and your engine runs like a top afterwords, let us know.

I always view those products as something used to patch a problem long enough to unload it on someone else.
If it worked, my Cadillac forum would have praised it long ago. Northstar engines in the 90's had a design flaw that caused them to blow head gaskets. It happened to us. We sold it, full disclosure, for a fraction of what it was worth the week before.
