My Bj60 had a tube from the valve cover straight down to atmosphere. My HDJ 81 has a hose from the valve cover routed as high up to hood level then straight down to the wheel well. No evidence of liquid oil in 20 k km.
Thoughts on the oil catch can..

Sorry, finderscuba.
I haven't installed it yet. I got side tracked and forgot about it for a while. I just started working on it again, I kind of ran into a problem of how much I should hang it. I made a 3-1/2" drop bracket, because the other one I made was too high. After I made a longer bracket, and trial fitted it. I didn't like the way it looked, so now I made something in between with a 1-1/2" drop. I will just have to re-route the tubes a little differently, since there is other stuff in the way. It looks like it should seperate the oil pretty well, and I will be sending the blow-by back into the intake.

Straight down to the top of the wheel well? or the back/front? I'm just trying to get an idea of how high up the opening to atmosphere sits. Is there any kind of deflector on the end of the hose? or is it just a wide open hole? I know it sounds useless, but is there any way you could snap a picture of how Toyota accomplished this?
I considered doing something like that with my 1KZ, but was concerned with the potential for having the engine shut down in deep water.. and/or dirt/mud getting flung into the opening when things get messy.
Edit: to clarify, I don't think the CCV vent being there would cause the engine to shut down, but if the engine WERE to shut down in deep water, and the engine start cooling with the CCV hose mounted low in the wheel well.. there is the potential for.. problems.

On the HDJ81, Toyota runs the hose from the crankcase vent to the intake. The previous poster must have installed a customized hose. I too would like to see a photo.
almost fell off my chair laughing so hard.

It's just a hose. Blocked off the intake port and hose turns sharply up at the valve cover then down to the RF shock tower where it just ends. Think it is 5/8 marine exhaust certified hose. No oil comes out the end according to the 'finger test'. I dont't intend to test the 'swimming abilities' of this setup.
is it 5/8s or 3/4. From what I could see it was 3/4 but i could be wrong

For us rusty 40 owners, that crank case vent tube is a life-saver, my front drive shaft will never rust.

That's a positive spin on things - I just learned about this after getting concerned from the amount of leakage on my driveway.. thought it was a bad gasket someplace, glad to know it's normal. I was advised to connect a short hose and let it drip into the frame - that should keep one side of the frame rust free as a bonus..
What seems like years and years ago I was told this is not a good idea. Something about the acids and crap in the blowby oil = not good for dumping in the frame rails long term. Dunno...but I don't.
I was going to make a soda bottle oil catch to collect the oil.
I want this for two reasons. The first is to see how much is blowing by, and the second is to stop that source of oil underneath my rig. I have some other leaks to track down and the wind blowing that oil mist everywhere makes it a bit tought. Plus, while not thinking checmically, I plan on redoing my frame and the last thing I want is oil all over it....
For those interested, the way to make the pop bottle collector, you just cut a soda bottle in half, slide the top half onto your blowby pipe and tape it on with something that can resist heat. Make sure to poke some holes in the neck of the bottle before this step.
Then, push and form steel wool below the holes you poked, but above the end of the pipe. Pack tight or find some way to glue it into place., then tape the bottom half of the bottle on. The wool makes the oil condense and fall back into the bottle, while the poked holes let gasses out.
I read about this on a thread here (no idea where it is) and have yet to try, but since I am going to install a new tranny soon, I'd like to clean up the underside and fix all of the easy leaks before I get under there for the afternoon.

Hey, Adam B. Where did you find your oil/water seperator? I was looking for something that small and light, before I found the one from Princess Auto. It's too late for me now, but for future reference, I would use that one.
Pretty sure mine was from Home Depot and probably cost around $25 plus the fittings.
Any place that has a half-assed assortment of air tools and fittings and a few over-priced compressors should have either the CH ones or Husky and they're identical except for the name tag and the colour.

Sorry, but there's no way in hell I'd install a taped up soda bottle under my hood. Somebody might see it
Not permanent. Eventually I want to install a real catch can, but I still want it to vent to atmosphere. If oil escapes and coats the intake, it makes it hard for diagnosis of a failing turbo seal...

Not all Land Rovers are useless!
Just a thought....(it happens every now and then), does the oil mist that is blown through into the inlet pipe help cool the impeller blades in the turbo? Bearing in mind that turbos have been known to glow red hot and the oil mist/air which is at crankcase temp would be at a lot lower temp and in conjunction with the the air from the filter be beneficial?
