Actually they weren't that bad, but the car had been sitting for a long time and I couldn't find out when was the last time my brother did a tuneup (and there's no way I could have asked him anyway...) so I decided to replace all of the usual stuff (plugs,wires,filters,oil, pcv valve); in fact the problems started after the tune up, after about a month I started noticing a blue puff when I started the engine every morning and that's why I decided to do the dry compression test and the results were:

Cylinder Stroke 1 Stroke 2 Stroke 3 Stroke 4
1 60 90 120 130
2 60 90 120 125
3 60 90 110 110
4 90 110 120 130
5 60 70 80 80
6 60 70 80 80
7 60 90 110 120
8 60 70 80 80

As you can see numbers 5,6 and 8 are low compared to the rest, I know there is some tolerance for lowest and highest values but I don't know how much percentage that should be.
