Eric...

Pegasus racing sells this exact product.

I have one in my car.

My problem is that the K&N breather on top of the catch can vents too much vapor, and it is quite stinky and not so nice... My idea is to have the breather can full of foam, to catch the oil, and then attach the K&N vent outlet, back to the air cleaner, or the manifold. So that it vents the gasses back into the intake, as the system was originally designed to do, but keeps to oil *out*, which is our main concern.

I think Crank case vacuum is the first priority, and making sure that this vacuum is being drawn from the proper places. Z will figure out how to separate the oil eventually - I know he will - but I also want to make sure not much oil actually NEEDS to be separated ANYWAY.

So you draw all that through some steel wool inside and outside the engine, so that oil drains back to the engine - and the output would be somewhere in the exhaust?

Do we have any diagrams?

my only concern w/foam other than possible saturation & blocking is that foam has a tendency to breakdown in oil after prolonged exposure - would not want chunks of foam finding their way into places they don't belong...seems as though if there is a bit of vacume in the crankcase, there would be less mist, since there would be less air for the oil to mix with- ie denser, heavier oil vapor - maybe less likely to waft out....

I'm going to look at my block to see if there's another place that might be more suited to venting - what possible harm could another hole do?(that's what colby bryant thought too) ....the dual pvc valve thing sounds inviting....under engine off conditions, pressure/vacume drops to open an oil return line to drain the collector....hmmmm....

I'd like to add a few things:

Don't put anything in the engine that might decay. Certainly not steel wool.

This isn't something everyone needs. If you like to red-line the car in 2nd, 3rd and fourth, then maybe it's for you. Autobahn speedsters (in Europe or not) should consider it. For racers it's a must.

The coolest set-up I've seen is by Eric from Denmark. He used a second early oil filler to fashion a separator. It's parked on the front of the engine and looks stock.

I've attached a picture of the one I made. No comments on the protography. What it shows is a decent one made from 4" PVC.

The inlet is near the top and there's a length of tube that wraps around the inside a bit to get a vortex going. Inside are a bunch of plastic scrubbing puff ***** to catch the oil. The ***** are held up about 4" from the bottom. The outlet is on the top and there a tube that sticks down to the bottom of the filter *****.

Along the outside is a sight glass made of plastic tube. There's a drain valve on the bottom. The top is a domed cap and there's a breather on it although sometimes I run an outlet hose back to the manifold. The bottom cap has a thread-in plug so it's flat and there's a brass nut cast into the bottom to mount it.

I put it on the shelf where the cruise servo sits. I drilled a hole in that for the drain and it bolts to that. Some tie wraps to the fender liner bracket and it's good. A bit of hose below the valve clear the body.

hey glen, nice setup! what do the scrubber ***** look like/where did you find them? (ever since my wife took mine I've wondered about many things)....
