High pressure fuel pump need to be removed to replace pcv?

It's a 2.4l ecotech engine. The pcv was replaced do to oil leak. And now they are saying that oil is getting into high pressure fuel pump. But it never happened before the leak was fixed. I saw a video where a mechanic removed the high pressure fuel as part of the pcv replacement. So that is why I was wondering if common to do so. Because if they disconnected it during repairs could that be why something happened to it. Waiting on dealership to call on Monday to explain what is going on. But wanted to have a little bit of ammo in the chamber if I could if they say I have to pay to fix it.
