I have an oil separator on my truck and not the CCV filter. I’m just curious if anyone knows how to tell one is bad other than throwing an engine code or is that the only one that it would tell you that it’s bad?
I've wondered the same thing about the sealed separators on the 11-16 trucks. I would think if the separator was clogged or not working the crankcase pressure would increase and potentially cause oil leaks. This could be verified by pulling the oil fill cap with the engine running to check for excessive crankcase pressure. Here is a video of the oil cap blow by test before and after a CCV filter replacement.
That’s what I’m trying to figure out because I have oil being forced out of the filler neck tube which could be a bad O-ring but that’s what I’m wondering is is it building up pressure to push it out through that O-ring or is it just the O-ring bad
Why switch to the old style CCV ? There are many videos on just changing the filter out. Is the old design better ?

Old style does not have a filter inside like the serviceable units so it won't stop up and cause excessive crank case pressures.
Why bother replacing the filter if it's just going to clog up in 30-40k? Best to replace it with the old style and forget about it for another 100k.
It doesn't make much sense to add a replaceable ccv filter if it will cause pan gasket leaks when it clogs up. Ford trying to fix one problem by creating 2 more.
Not a great picture, it’s hard to get a good shot. This is what’s on my 2020 F350 SRW SB. It doesn’t look like the same type as what’s in the video though. Anyone know wether this type has a filter that will need to be changed (I will periodically check for pressure under the oil fill cap.).
yes all 2020's have the newer style CCV. just remove the bolts and pull the filter out/replace. Oil dipstick bolt and the ground strap removed for easier access.
Part of the weekly maint needs to be checking for excessive blow by while running as the truck ages. My suggestion would be somewhere around now for a baseline and then starting at around 30K.

Hey Dirt, what did you mean by "forget about it for another 100k?"
The old style just allows the oil to drip back in. There's nothing to clog up like a filter. Why would it have to be replaced?

I don't know if the sealed unit requires service at some point but it would make sense to me to replace it every so often since it could potentially become loaded with oil.
