So i put my gov spring in this weekend and today i went to start it up and popped the hood. I noticed the pump was leaking. Not like little drops but full on leaking. i know i tightened everything and double checked it. It only leaks when i start it up after its been sitting a while. After about ten minutes of driving it stops leaking. Does anyone have any idea as to what might be causing this? I'm a little befuddled. Thanks in advance.
