When I soaked the head in the solvent tank, I could see solvent oozing past the plug so it needs to be replaced. I have never seen a head with a plug, my first thought is that it was butchered by previous owner(s) but i have been googling and found it was common on the 1275's which explains why I never saw one, this is my first 1275. So what is the best repair ? I can get it out and machine a new one to press in, that won't be a problem but I foresee the same problem in the future. I would be scared to try taking it out and threading the head myself and I think I would send it out for the threading part or is it pretty easy ? I read on one web site where the guy drove a screw through the plug all the way through to the other side of the water jacket (not through the jacket just touching it) to keep it from recessing again. I would not do that but could easily machine a plug with "stub" on it that would rest on the water jacket to keep it from recessing again. I have a lathe and mill but I am not a machinist, I tend to make more shavings than usable parts, I don't mind making a plug and skimming the head but threading cast iron myself seems like asking for trouble, but maybe its not if the head is thick enough.
