Bit Of Advice Needed Please

Hello fella's

Well I am a new member to the forum so a quick Hello first of all!!

So I have just bought myself a 2003 1.8 lx mondeo, The car has no MOT but it was very very cheap so I thought I would give it a go and try to sort out what is wrong with it. The lad I bought it of said that it had failed its mot on emissions ( will put the levels down below). Was just wondering if anyone could point me in the right direction to rectify the problem. It smokes really bad when revved hard and seems to be a little under powered. I was thinking piston rings maybe? And if so are they a pain in the backside to change?

Exhaust emissions carbon monoxide content at idle excessive (7.3.D.2c)

Exhaust emissions carbon monoxide content after 2nd fast idle excessive (7.3.D.2b)

Exhaust emissions hydrocarbon content after 2nd fast idle excessive (7.3.D.2b)

Exhaust emissions Lambda reading after 2nd fast idle outside specified limits (7.3.D.2b)

Exhaust emits excessive dense blue smoke during acceleration (7.3.A.1c)

Cheers, Deano.
