That guy had a fifth gear. Rat bastard. But we BOTH had SEGs, and there wasn't ANY other traffic. Dude absolutely knew how to drive. Me, not so much. I was trying like hell to avoid 5,000 rpms, 'cuz oil pukes out the breather box after that. Still haven't quite figured that out. If I had a reason to open it up completely, I'd just mop it up later and not worry about it -- but I had JUST cleaned the chassis thoroughly the day before, and didn't really want to do it again.
That's a lot of surface area to wax, you see.
Lovely 911, though. Pale purple with black trim, with the standard-issue polished Fuchs. Very pretty. Reminded me of Gordon's wheels.

Sounds like you've got either a too-small breather box, too small outlet(s) or too small hoses going from the outlet to the carb air filters (or all of the above).

Sounds like the case is breathing in OK, but it's getting choked at the box AND somehow accumulating too much oil in the mix as it can't dissipate fast enough. Phooey! You don't want all that precious oil finding it's way into the air cleaners, cuz THAT's just a bigger mess to clean up, not to mention fouled plugs and all the fun that goes with it. think about it this way: the stuff's flowing in under slightly positive prressure, and getting sucked out under slightly negative pressure. As BOTH of those pressures increase with RPM's, what's supposed to slow it down inside that dinky little breather box? The foam insert? I don't think so!

So I would look at a MUCHO bigger breather box. I remember seeing a few 356 racing cars back in the 60's with Hi-C cans mounted vertically on the firewall with the inlets attached about mid-way up, the outlets up from the top and the drain-back in the bottom. I often wondered why they were so big - maybe now I have an answer. I bet'cha they were stuffed full of that steel scrubber stuff that looks like a "Chore-Boy", too, to assist in oil vapor capture (the 60's version of your (saturated) foam insert).

OK, so a Hi-C can might be nostalgic, but not very pretty, no? Maybe try looking for some sort of attractively cast or molded box (aluminum or ABS would do - inside temps likely not to get over 300F) of dimensions, say, 3"-4" thick, 4"-6" wide and 8"-10" tall. Plumb it like the Hi-C can a par. above, stuff it with a couple of metal Chore-Boys and you should be good to 6,500 and higher. I think it's important to mount it vertically, with the inlets in the middle or near the bottom to allow the oil to separate from the air and fall to the bottom, not go out the top. CB's oil filler/breather box has little curved vanes cast into the inside of the box to capture the oil and drain it back down. Something like that would work super, too, IMHO.

Commander Cory! The Terror of the Beltway!
