Yes I did that as well several times this lead me to pull the Engine out and do it on the side because I'm tired of pulling out putting the IP back in again and again over and over , but maybe the when Bosch rebuilt my IP it was not set to 15 atdc I have to do it myself when its install I don't know . but sorry cristuna I have to admit I'm not good at this , what you mean looking through the port side of the IP and what is the locking tools can you show me the picture this whole thing ?
