Poured lead cleanout

I had a kitchen sink back up on me last night so I decided to snake the cleanout. The plug and a liner came loose from the lead. I was able to pry the lead out, but now I am left with a 3" cast iron pipe with no threads and no plug. I put in a plastic test plug as a temporary fix, but is there a way other than pouring lead in again as a permanent fix? I can add a picture later if it will help.

I think a 4 inch gem cap (rubber cap with hose clamp) will fit around a three inch hub, then you can tighten it up and it should be good.

The same thing happened to me at my daughters house about 2 months ago I did what broox recommended and it worked good. She even had a main sewer backup and I could tell by the pressure on the cap how far it was in the pipe.

Just make sure you get the band nice and tight.

Another solution would be to refill the joint with oakum and PC4.
You will have to pack the oakum in first with a hammer and the proper tools, then use the PC4, soaked in water, and again packed in the joint.
You will not like the price of the PC4 as I believe it is quite expensive as it comes in a large can, enough to do many joints.
I would suggest you follow the advice from the above posters and try to find an approved rubber cap that will fit over the hub on the cast iron pipe.
