I wanted to wait till spring to do this but it's too late now, I started. Exhaust stud on #4 is broken below the plane of the head. I can get a regular drill in there. I've got a set of timesert inserts and the tools to put one in. Is there any chance at all I can fix this with the head on? If I pull the head, I'm going to have to have it rebuilt, then I'm going to have to rent a valve adjustment shim set, and buy a bunch of gaskets, why not a timing belt and water pump while I'm in there? and maybe the cam doesn't look so good, and how's that bottom end after 240K? See where I'm going with this?
So I guess I need cobalt? or diamond bits? And they should turn the reverse direction? Does anyone want to talk me out of trying this before I start and tell me to just pull the head and take it to the machine shop? Has anyone sucessfully done this with the head on?
As always, thank you for your help,
