Why use a drain plug when a valve will do?
I just use the dumb drain plug. Mine has been in and out and in and out and in and out for over 200K. All that wacky stuff from Lawrie about replacing plugs & chasing threads & making it all complicated is apparently if you’re incapable of removing and replacing a bolt without messing it up. Its not rocket science. Its really easy. Take the bolt out. Let the oil drain. Put the bolt back in. (Nothing wrong with the valves either).
