lead and oakem replacement

Is there any kind of treatment out there in the market that will replace the old lead and oakem seal in a cast iron pipe?

I had a plumbing job done a couple of years ago where the laundry area was renovated and PVC piping was installed directly into the cast iron pipe that is the drain pipe.
It appears that they used lead and oakem on it and that the oakem has come up near the pvc pipe and when the washer runs, a small amount of water does come out at the top
of the cast iron pipe where the pvc joins it.

Take the large end of a punch, old hammer handle, etc. and tap the lead down around the oakum. That should seal up the joint.

hot lead poured around plastic? hmmmmm. i would have used a ty seal (rubber gasket) or cut the bell off the cast iron and used a banded transition coupling instead of trying to melt the pvc.

but as mentioned tapping the lead back down may stop the leak
