I concur, seals letting oil by and the blower pushing it down the pipes with the air.
You're basically feeding your engine an air/oil vapor mist. LOL

Doesn't the engine already have a air/oil vapor mix due to the PVC? Lol

Yea... but that's why we buy oil separators lol.
And it looks like quite a bit more than it would pull from the valve covers.

I had a ton of oil coming through the PCV system into my supercharger elbow and throttle body on my M90. Turning around my JLT oil separator so that the screen was on the inlet fixed it.

You have no vacuum pulling PCV gases out of your crankcase at all? If you have breathers and vacuum to your inlet piping, your system is tuned for this vacuum leak?

Open filters and a large PCV line would mean a ton of flow through the system and into your inlet piping. You'd definitely want a real separator (see the rebirth thread.)

Your not understanding a breather setup, there are no hoses on the intake or manifold to pull any oil vapor in. The breathers on the valve covers vent crankcase pressure under boost and keeps oil in the case where it belongs, then you cap the intake/manifold so no vac leak.

I know the op is trying to be comical about it, but you can seriously blow your motor with that much oil going through. The oil vapor will dilute your air/fuel and if your blow through you will get oil on your maf messing up the signal.

I understand how breathers work. That is why I put them on there in the first place. What I am meaning is from the factory, doesn't the PVC system already let oil back into the intake through the intake arm?

Def. oil coming through the seals, or being drawn into the intake attached to the blower from the valve cover. My Vortech has minor residue in there but not quite like that.

Yea. No PVC system is hooked up.

I read he has two filters, which match up with what ports there are on the valve covers, I was just kind of hoping there was still a line added to explain the amount of oil in that intake tract. Maybe without a PCV you end up with enough reversion to get oil out of the intake anyway? Strange things happen. My 5.0's upper intakes always had oil in them, and they were a long way from the PCV system.

I bet the superchargers don't hold a whole lot of oil, based on the evidence in the intake if it is from the gear case it's probably mostly gone. Easy to check.

Check your return line to the pan, might be kinked or pinched not allowing for oil to properly drain back to the pan. Worth a shot but most likely a seal issue.

Well seems to be a seal. Anybody ever replaced the rear seal themselves? Or front?

I've read where some guys say the rear seal is the same that you can get at freakin the parts store for like $10? Crazy.

I plan on just doing it myself and posting pictures on how to for reference for others

Usually seals fail for a reason. A good reason is bearing failure.

Billy 05Stroker has rebuilt his Procharger. He probably knows where to get parts.
