That's not correct.
There are almost always passport checks when entering Eire from the UK. (I've only not been checked once in about 20 trips).
There are never passport checks when entering the UK from Eire.
Also - bear in mind that, although it's possible to enter Eire from Northern Ireland (without passport controls), if you enter Ireland without a visa, you are in the country illegally. If you should, God forbid, have an accident or be involved in a crime, you're likely to be in major trouble.
