But then, even new engines experience blow-by. I'll see what it looks like after this oci is drained.

That thought did cross my mind. Higher than usual rpms sustained for 2,000 miles during this oci, I should expect more blow-by I think.

Me neither.

On mine, it's easy to think you have it completely sealed while it's actually not on the bottom. You really have to know to look for it.

I think there may not have been a point but not sure.

No pre-filter, but the leak would bypass the filter. Theoretically, my filter would last longer but my engine would suck dirt.

I did catch myself once not sealing at the bottom side. That seems to be an easy mistake to make on this design.

UPDATE: My new Motorcraft air filter arrived yesterday. My old filter @ 17k miles was dirty as hell. Almost no sunlight would shine through it. Haynes says to replace every 30k; I will change every 15k from now on.

I had always assumed my engine was clean based on my drains looking pretty translucent and reddish, for used oil. Certainly looked nothing like my oil changes in the 1980s. Today's oil drain looked like I time traveled back to 1985 and drained my 390, but no lumps or shiny stuff.

I always use Motorcraft filters.

I used to run the m1 hm 5w30 but when I wanted to switch to 5w40 I couldn't find HM in 5w40. Do you know of one that is synthetic?

I will change air filter today. I can't find a HM oil in 5w40. Do you know of one?

I did just change the pvc 17k ago.

I did check pcv and it does rattle freely.
