I am very interested in the oil separator, do you know the brand name?
Thanks, Nick

think a windage tray would help?

Actually, being the rookie I am, I'm still trying to figure out what the good Dr means by 'factory oil separator'... Are you talking about the vent on top of the valve cover ? The only separator I can find any information about is the fuel/water separator.

I understand everything else about the concept, but where is the source, or OE separator, located on the engine ?

oil separator is basically a catch can, serves the same purpose. the OEM one is on top of the valve cover above cylinder #4. on the gas 1.8L 8v its the round disk looking thing connect back the intake.

They're commonly referred to as hockey pucks, I guess because our neighbors to the north love vw diesels almost as much a hockey, and is located atop the hole in your valve cover opposite the oil filler.



Is there any reason this setup would be preferable to a regular catch can?

in my case,  a windage tray AND a trap-door/baffled oil pan is in use.
I want to believe that my runaway issue was caused by oil pooling on the driver side of the cylinder head and being blown out the crank vent. I have a sneaky suspicion, however, that the quantity of oil supplied to the head during that onramp episode is significantly less (especially considering some return via driver-side drain hole) than what ended up in the intercooler. It seems possible, if not likely, that oil in the pan might be piling up so high that it overcame the windage tray and  was obliterated by the crank into vapor.
A close look at oil pan design might be in order, some day.  ::)
 
as stated above, the 'source' of crank case air is from the circular black plastic separator on the top of the valve cover (AAZ also interfaces with a fitting on the block near the vac. pump).
I repair, maintain and modify VW's and BMW's.
Good work done at affordable rates. Welding and fabricating, too.

^ I thought I read he'd built it using a seperator from TSC...

I too have an AAZ, so I've got the windage tray but I'm still getting a lot of oil in the intake... I plan on installing/fabbing up my catch can today and we'll see what kind of difference it makes. The ports on it are fairly small, so my only real concern is whether it'll flow enough air out of the crank case. I guess we'll see if my dip stick is pushed out or not.

I can't imagine why 18 year old economy cars are having issues with oil in the intake when we're driving them like sports cars lol  ::) ;D

or a CO2 paint ball tank... they are cheap small. then keep the fire extinguisher for just in case fires

You may notice I mentioned that earlier... ^



Yeah, scary stuff when you snuff the air intake and you hear it just start drawing air in through the valvecovers and everywhere else it can suck air in... And it just keeps running... There's some fresh brick work in Fanshaw College because of a runaway diesel.

Ians shop? He used to teach hydraulics IIRC, and once had a hose let go whip around and take out a cylinder arm.

No room, it's oriented so that it will still function correctly, and will drain to the block. It's hard to tell from that picture but the crank case vent/drain at the front is just about the lowest point in the catch can so it will drain back into the block. It does have a steel wool medium in it to help draw the oil mist from the air. The line running to my intake is still completely clean, so it must be doing its job.
