Not true. What engine? There are a couple of types you can buy, brass and a rubber type that expands by bolt for those areas you can get into easily. If you can get to the casting plug hole, use a new brass plug. If that doesn't do it, use a new plug with some silicone. You need to make sure you use the right tool to drive the plug into the block. If the diameter of the tool is too small, it will not seal properly.
