This sounds fairly close to what he was trying to explain, although he did mention a copper crush part. I will observe it to see if I can locate more precisely where its leaking, I assume he did also and concluded its not the injector itself. What type of shop would do this work? A head/valve machine shop? A diesel truck shop?
