Did you install the catch can from day 1? Could the oil have got there prior to catch can install?

Have you looked behind the throttle body where the pcv returns...in coming tube from the catch can? If it is dry around the tube inlet then the oil is coming from somewhere else.

What about the clean side seperator? Never hear about this. Can you explain better. I also have the elite 2. but i hope the oil problem was solved for me

Just til today, i have seen this thread

I installed it on day 2 of ownership, day 1 was very minimal driving and wouldn't have caused this.

I'll have a look soon at the inlet from the can to the snout and see.

It's easy to see with a flash light by just removing your air inlet tube.

Your 30 ml in 7,000 mile is low. I think your not catching very well. I get 15 ml (not measured...just visually guessing .5 oz) in 500 miles.

Hi GenF-GTS,
What did GM name your car over there in Australia? Nice looking ride, Cheers. Thanks, Sam.

Update:

Tonight after work I removed the throttle body to have a look from this angle into the snout and also look inside in the intake tube + clean side cylinder attached to intake tube.
I was able to find a small amount of oil on the inside of the throttle body once removed, you can see it in this picture around the gasket at the bottom:



The intake tube looks clean there are no traces of oil in it, here are the pictures as best i could to get one with the right angle to see into the breather tube. If this was leaking from here wouldn't it leave an oil splatter coming out from the tube into the throttle body?





I then removed the return line on the catch can, as it has the AN fuel line type fittings i had to cut it off, so here is the cut off piece....the dry area is where it mounted to the fitting, the wet area is part of the line that would have seen oil....as you can see it is wet with oil. (This is the return line going to the manifold)

That little bit of oil in the top end is meaningless. Quit worrying about it and enjoy the car.

It's actually helping lube things. The OE setup does pretty good in recircing the vapors back to the crankcase and burning off that little bit of oil and vapors. A catch can will help a bit more to catch the heavier liquids.... but in a non direct injection engine, that little bit of oil burn is meaningless. On a DI engine, too much intake oil can carbon up the intake valves because there is no intake fuel to wash it off.

Even with a catch can there is still oil in the vapors going up into the intake that will settle out in the low spots of the intake under certain throttle conditions. It's just sit there and look ugly, but affects nothing.

If the car is driven so hard in cornering that the valve covers are getting flooded from the G's... like during a full day of an HPDE track day. Then there will really be a lot of oil up in the catch can and intake. Empty can, don't worry about that little bit in the engine. Engines use oil for lube, that little extra up there will do nothing.

If there was so much oil going into the intake to actually affect things, it would be smoking, spark knock, power loss... When just a minute normal amount... normal power, no smoke, no knock, plugs will look clean, normal oil consumption... and there will still be that little bit that pools here and there in hte intake... meaningless.

If it were antifreeze, I'd worry. Oil... engines don't mind a little upper end oil actually helps lube things. When it becomes too much intake oil, it will be very obvious in performance, knock, oil consumption.... Normal oil consumption, I'd ignore that little bit up there.

So I wonder if other people have checked this with their catch cans. Seems like quite a bit is getting past it.

Opinions aside the catch can is suppose to catch most if not all the oil.....

To me it looks like there isn't enough baffling/restriction on oil vapor flow and it's able to get through and back into the engine.
(personally If i designed the can it would also have mesh and baffling on the outlet to help stop what is already in the can going back out of the can, vacuum works easily but restricting oil flow and creating a maze for the oil to exit through is always going to work better than just having a straight exit port on the side of the catch can. I think the design of this can is good but i think it certainly does need improving on)

Whilst the catch can is catching "some" oil it certainly isn't doing an effective job it should be getting a large majority.

Honestly I made that video only a few days ago to tell the guys who also own the same car to fit the catch can up. Then a few more days later when i took the top off the supercharger I was expecting it to be pristine and free of oil....the plan was to take a photo and post it up on the HSV forum going here is proof of why you need an elite catch can....look how well they work.

Sadly that isn't what has happened.

I have a 2nd catch can another E2 from Elite, I will be getting my OTR fitted and tuned in a couple of weeks the plan is to plumb in the 2nd catch can very low down with lots of length of oil lines along with the glass fuel filter....I do not want any oil going into the engine. Thats what the catch can was suppose to do. Now i will go to extra lengths to make it happen myself.

This is how i would have designed it, as said vacuum will not be effected by the maze it always finds it's way but oil vapor on the other hand it will not like an uphill maze with wire mesh.

Two things:

Get a RotoFab CAI.

Install your CC inside your CAI...problem solved.
