Repair of the Nissan Sentra B14 camera

Good friends, it turns out that my Super Sentra was passing the compression to the refrigeration system, so it takes it to the rectifier and the problem is already corrected, but it turns out that it damages the upper tensioner of the time chain, so I had to buy it but when putting together again and turning on my car, the chain looked and the problem is precisely because with a hose it is possible to identify directly. Which do you think the problem can be?

The problem is already solved, by distraction on the side where the tensioner does not leave the chain a longer tooth but now I am smoking in high revolutions. .
