1998 grandprix 3.8 no supercharger
Dad broke a plug off in the rear bank, only the threads remain.
My plan was to remove the rear head and repair it on the bench. I've heard a few people say that it's easier and cheaper to pull the engine to gain access to work on the plug hole.
If it turns out to be easier / cheaper to lift the engine we'd fill the cylinder with cotton, wax and grease so that we can drill and tap the hole while the head is still on the engine. I can scope the cylinder when done to make sure that it's clean.
I'd have to hoist the engine. I don't have a lift, so I can't drop the front end out the bottom.
Thanks
