Testing Air Oil seperators

[JimiJak]

Is pressure on the IM what closes the check valve in the valve cover?  Just wondering since the Rx can would fix that problem.

Yes and correct.

Update to my first OCC drain and video + CSS re-route posted on original install thread!!

[ShoBoat]

I managed to suck the crap out of my CAC, (not fun) I plan on pulling the tubes off the turbos tonight to see how much if any oil is in these tubes just after the turbos (back vs front) I am determined to figure out exactly where the oil is coming from and how much from where.  In my CAC there was a measurable over 1/2 inch (more like 3/4) at the bottom of the CAC. I don't care who you are and what your experience is, that can't be good. And FMC or anybody else if you are trying to tell me that's normal? I don't think so.

Sounds like the IC could use a drain plug!  Did you disconnect hoses to do this, Shoboat, without having to pull the unit out? N/M, just saw your post in the other PVC thread

I know of an ecoboost cruiser at the dealership right now with oil in the turbo. hopefully they will investigate before and after the turbo.

This is exactly how I did it, I pulled off the intake tube from the TB and CAC. I then attached a 3/16 washer tube to a compressed air cleaner like this. The compressed air cleaner has a port for chemical or water. Using Venturi it pulls the oil from the bottom of the CAC. I decided to do it this was as there is minimal risk of fire or explosion. Using an electric vacuum the vapors must travel through the head of the vacuum. If there is gasoline vapor there is the risk of FIRE! So better safe than sorry, unless of course you have access to a vacuum that is explosion proof and rated to pick up flammable liquids.

I then inserted the clear tube into a 3/8 fuel line, this was necessary as the thinner tube did not have enough rigidity to stay straight as I dropped it into the CAC.

I then inserted this tube down into the CAC, plugged the cleaning wand into compressed air source and put the discharge into a garbage can with a plastic bag lining it. To avoid getting oil all over the place.

I tested oil level after with the dipstick from the car, when I started I had about 3/4 of an inch of oil in the bottom of the CAC. When I was done it didn't really register. I also did a bit of wicking like this. Just to ensure I got as much as I could out.

And the final operation, I must stress that extreme care be taken not to drop anything into the CAC. If you do the only way to get it out is to remove the CAC from the car. Also if you do the wicking use non shedding lint free material. I used acrylic string just to be safe.

Excxellent idea!! This will make it SOOOO much easier to do, and this is critical to prevent hydro lock in the future as in say your cruising don the highway and have to pass a car....floor it and that sudden jump to max boost can push that mix in to the IM in a "gulp" causing hydro-lock and broken pistons and bent rods.

[ShoBoat]

I think I'll do a better write up and put it in the how to. That will make it easier to find.

RX OCC - RE-MOUNTED OUTSIDE THE ENGINE BAY WITH REMOTE DRAIN ON XSPORT.

SHOboat; Wondering if I missed a post somewhere...

What ever ended up happening with your oil separators?

[ShoBoat]

Not much as of yet, my last inspection had some oil in the tubes leading to the separators. Nothing visible in or after the cans. Also there is no evidence of new oil in the cac or the throttle body as of yet. I am going to take apart the system this weekend to take a look and I'll let you guys know.

Excellent, thank you for the update!

I had my second 500mi. Rx drain today HERE.

[ShoBoat]

So I tore the system apart last night, and nada, nothing zip in the cans. 2 tanks of gas about 900km. There is evidence of oil in the tubes leading to the separators nothing in and nothing after. I am beginning to think that either it's going straight through or it's too restrictive and not getting into the cans. Weird, I thought the pcv side would get something. I'll have them on for about another week and we will see where I stand. But it doesn't look good for the morso cans.

No signs of any oil/misc compounds coming to a rest in the catch can, no matter how brief?  The Moroso can does not use coalescing material, correct?  I wonder if an internal packed layer of steel wool would help.

[ShoBoat]

It does have filtering material at the inlet and outlet. I'll take some pics when I get them out again. But nada in there.
