I had a small thermastat housing leak Im repairing. In the mist, I was contemplating drilling a hole in the thermastat. Like we’ve all heard or understand. Drilling a whole will help the engine warm up quicker. Well, wouldn’t this be the opposite of that theory allowing the engine to take longer to warm up being coolant would be allowed to leak to the head through the drilled hole ? Thus, taking longer for the engine to warm up upon initial start up ?
