Well I guess you can see if it'll fit
My AIR/OIL separator install on 1996 Mark

Yeah, I'll go look at it at the store and see.
My only concern is, did you see they say "self empty" or something along those lines. When there's no pressure, it empties. As long as that's not happening while driving, it'll be fine. However, if it happens while driving that would be a vacuum leak.
EDIT- I could use the first home depot one and use 1/4-3/8 adapter....

Or am I thinking wrong?

Dunno about the self emptying, think it would make a mess..
I would be worried about using one with 1/4" openings. The PCV is venting the crankcase pressure. The intake manifold pulls a vacuum and reliefs the pressure on the oil seals. I wouldn't want to restrict the line any more then necessary.
My suggestion is to find one as close to the jegs design as possible. Maybe take some measurements before you go into the store

Gotcha, thanks.
I'll look at the specs on the JEGS one. This one is rated at 90PSI which seems to be the average for most of the ones I'm looking at. When you step up to a little more expensive, I saw 150PSI a few times.
Appears to be the exact same thing, actually. 1/4 x 3/8 barb. It has a slightly higher maximum PSI though. The can height seems to be the same too (5").

Designed for vehicles with positive crankcase ventilation systems, this air oil separator prevents oil blow-by from being displaced into the intake tract on engines where crankcase pressure is high, such as high RPM applications. When installing, always route separator away from heat sources. Highlights Maximum pressure 150 psi Clear polycarbonate bowl for easy viewing and durability Serviceable 5 micron element Twist/turn drain Mounting bracket included Two 1/4" NPT x 3/8" hose barb fittings included Easily cleaned with dish soap, a thorough rinse, and air dry only.

Also, I just finally looked at what I'd be doing.
Remove the F and run the hose from the PCV valve to the can. Second hose runs from the other nipple of the can to the line that the PCV valve elbow was originally connected to, correct? (the one that leads to the emission T in the back).

Alright, sorry to continue posting so much but just an update. I went to to Home Depot and checked out that first one I posted, and it was in fact rated for 150PSI max. The specs are identical to the JEGS one, except the JEGS one looks nicer. Possibly higher quality material, not sure, but this one is solid.
I bought everything and put it together. Price including all parts, bracket and 3 feet of hose was $28.xx. I'll hook it all up tomorrow and see how it goes.

That'll work! Looks very similar to the jegs. Looking forward to see how you mount it.

I'd recommend putting a motorcraft pcv valve in there. Also is the top F open to atmosphere? If so you want to plug that off
No no, it's plugged. It came with a little plug.
I changed the PCV about a month ago, just because I wasn't sure when the last time it was changed. I plan on buying a Motorcraft off eBay. It's about $8 or $9. These cheap ones, you can't remove that "F". I tried before I finally decided to just attach it like that.
I wish it looked more factory, like yours. If I get some brass elbows, I can clean it up. I work for a propane company so I'll see if I have 1/4 x 3/8 elbows at the shop, since I have a huge variety of brass fittings there.
