Calling all diesel guys!

I have seen both happen. What we always did when one came in with that issue was retorque to spec and check to see if it leaked afterwards. Plus it’s free to check that. We didn’t even charge for that step if that solved the problem cause it didn’t take long at all, half the time it was done in the driveway.
I think that's what I'm going to try first. I'm fixing to order the pump so the truck will be getting it all done at once. Hopefully that will fix the weep.
