best regards.

Thats very common with any oil soaked or carbon impregnated casting.

often, it requires welding a little bit, then burring the weld back out with a carbide burr, then welding again, etc...until the metal cleans up.

its good to do a skim cut with a carbide burr every pass also so you dont get finished and have a bunch of holes as a surprise.

4047 filler can help too
