Unrelated. Question but since I have some avid users here ill ask. I have a diesel lea k, it's not my delivery valves as I did those last summer and I can tell. However the lines hav nt been done but they don't seem to leak, it's leaking from around the ip not sure exactly where... Do you guys know of any common culprits besides deliv valves and clear lines?? Also since this will most likely require intake removal(it always does) what else should i knock out while I'm down there?
