Comments to the above posts: Although, the driver’s side valve cover can be replaced in 4 hours, the passenger side has a cam driven high-pressure pump and more harnesses to deal with. Ford recommends both valve covers be replaced in the TSB after a lengthy diagnosis TSB.
As some of you may know, Ford will quote both the diagnosis TSB, and if more than 1 quart oil or more is consumed in 3000 miles then both valve covers are replaced. Hopefully, most of you are still under warranty. That was not the case, here, on the ‘17.
I’ve given extensive detail as many folks on this forum are after-warranty and will eventually encounter these repairs detailed in several TSBs well known to savvy Ford enthusiasts. I’d hoped that Ford would extend warranties for these TSB related to plastic parts failing to a broader cohort. After calling on Ford — I’d found that NTSB only requires Ford to extend warranties on plastic defects that imply safety related issues —— even though it could be argued that these defects occurred in manufacturing. There are several posts in this very forum that referenced hairline cracks in new parts. Gen 2, ‘17-20, appear to have the most posts on ‘driver’s side hairline crack in valve cover and oil separator valve TSBs.
[Gen 2, ‘17 driver’s side valve cover after replacement. There are nearly a dozen fir-trees on each valve cover. Do not attempt to pry the fir trees out as you’ll likely damage the wiring harnesses which is a very costly and time consuming repair. Use a very small flush cutter avoiding the potential to nick the harness —

When replacing valve covers it is necessary to cut the one-piece 1/4” hole ‘fir-trees’. Ford OEM are made by Panduit [PUM-071-2S-D30 —
