need some info
 

Okay guys i have a 440 AWHP evo VIII. It currently has a boost leak. My tuner believes it is a cracked valve guide. What kind of damage can this cause if it breaks? I plan to fix it i just want to wait until after summer when its usually off the road. Its only noticeable under full boost and not every time just once and a while. I dont plan to beat on it because of this but also dont want to miss out on having it for the summer.
