Hello everyone I have a goal Gl 1.6 barrel and began to fail as if I walked in three cylinders looking for the fault as if it were a spark plug but they all worked so it suspected that it would be a valve that did not open and so it was when I took out the valve cover I found three folded rods and three dried rolling I change all the rods, I have two queries if someone could give me a hand I would appreciate the first one is that I have to leave it and the second how I put it up of course thank you very much
