Bongo Fury

hi gu ys and i posted last august and my timing belt broke . I got the repair done and the cost £440 as not too much damage.... however the engine is sweating oil. What should I go back to the garage and say after a year?

What does sweating oil mean?
I would think that the garage wouldn't be interested after more than a year - you'd need to prove that their work was faulty, which won't be easy after so much time
