1 week(ish) follow up:
12/15 vehicle mileage 101101, temps high 30s to mid 50s. Can empty.
12/23 vehicle mileage 101394, temps low 40s to mid 50s. Can had 25mL of oil. AE9AFEAC-3B8B-498E-B5C3-EEB9EA48C69E.jpeg
This is after I measured. I’ll plan to let it sit a bit and see if it separates at all.

Pulled the can off today to inspect since I last did it 12/23.

Definitely some milky look in there now. Our weather has been consistent 30/40s overnight with highs in the 70s. I idle A LOT.

I didn’t measure this batch but it looked to be about 25-30mL. I also just last Thursday has a misfire while merging on the freeway, and again today while merging on the freeway, this one leaving the light on. So I need to have to code pulled to see what cylinder misfired. My plugs are just the crappy motocraft, but they are less than 15k old.

Checked the oil dipstick, shows my exactly in the middle of the max/min.

That one has water in it, and makes sense based on the temps. Still a lot for the time/miles, but if you idle a lot, that makes it make a bit more sense.

Did you set the gap on the Motorcraft plugs before you installed them? In theory they are pregapped from Ford, but in my experince 1 in 6 is right.

I did. I had my shims out just to measure the old plugs and then checked all the new ones to make sure they weren’t all janky since that seems to be the norm.

Just had the codes pulled, P0301 cylinder 1 misfire, P0300 random misfire, and P0303 cylinder 3 misfire. I’ll have to pull the plugs tomorrow or Saturday to inspect.

I don’t believe it is needed for the V8. I believe it is related to the turbo and ecoboost.

I have run across (on a different forum) talk of catch cans for the 5.4 V8. Has anyone here done that?

The idea seemed to be removing oil from the PCV which made for a cleaner intake manifold. There was even talk of improved MPG.

I really doubt that it'll increase mpg, but it would help with the smokey startup after a short run, like after moving the car in the driveway.

I have a 2017 EB with about 122k miles on it. The weekend before last, I installed the catch can in my engine bay. I checked it this last weekend and was surprised at home much "sludge" was in there after just a week of mostly city driving, maybe 250+/- miles. It looked just like what was in the original post that LokiWolf made. From what I've read, this is way more than I should have after just 200-300 miles. Does anyone have any input? Thanks in advance!

Did you put the sludge in a glass and let it settle so it will seperate? Is usually @LokiWolf 's first question.
I did not. I'll be honest and say I haven't read through this forum post by post. I just kind of hit the highlights. It was the tan color though and did have some thicker sludge type crap at the bottom.

Read about 3 pages right from the beginning and ordered a J&L separator for my '17 Expy which I purchased a few weeks ago (84k mi). Does the ol Italian tune-up work with this engine though? Figured I should do whatever I can to get as much longevity out of this vehicle as I can. Also have a set of Ruthenium plugs ready to install too.
