Remove the "Powerstroke" Cover above the fuel filter and there is an allen head plug on top, you/he should have oil about 1/2" below that. I know he did put a new IPR and ICP in it as well. LPOP is a decent thought though, simple to change and I have been so focused on thinking he has worn injectors that I did not think of that.
