Oil cloud

I would remove the RX breather. Too many issues with them causing rear seals to leak. Under boost you could actually blow out the rear seal then you have real problems.

Remove it and replace with what....the OEM cap. You still have the problem of nowhere for the cranckase pressure to vent. Easiest solution is to just remove the check valve in the breather. Takes all of 5 seconds.

I still havent had time to do this, let alone drive the car again. I am hoping to take a look at it all this weekend. I am still hoping there is no damage done, which at this point I am positive there isnt.

Oil change on the car today, definitely oil on things under the car.

Dealer is going to replace rear main seal under warranty.

OP - JRE has a valve cover breather with a check valve that lets pressure out during blowby but seals on normal driving to keep from sucking in unmetered air and skewing the fueling. They have one for OEM and threaded aftermarket rocker covers. Might be a good long term solution to building crankcase pressure. I use one.

Thanks I will look into it!

HOw is it "unmetered air" since under normal driving this little bit of air goes to the crankcase under vacuum. It never makes its way thru the intake tube and past the MAF. Under boost, obviously there is no air entering the unchecked breather but only excess crank case pressure escaping. I thought the valve not letting pressure out was for the EPA nazis. Even the RX breather allowed air in but no air out. Thats why you remove it. Always worked for me. Now i just run two bungs from my valve covers to a vented CC. Works great all the way up to 25PSI

It also looked like it was leaking around the oil cooler.

When that oil made its way past the rear seal it coated a bunch of stuff down there. At least on mine it did. My rear sear was fine after the fact so yours probably is also. Just drive it for a while and burn off all the residual oil and wipe it down best you can. Then check for leaks etc. Your rear seal probably is fine I bet

Well I had an oil change today, and when the car was lifted there was oil. We cleaned it up after the oil change and I drove it. Brought it back, lifted the car again, and there was oil again.

My inlet is after the maf to bank 2 rocker cover. Valley cover blocked. Bank 1 rocker cover to inlet of catch can. Catch can outlet to supercharger vacuum port above rotors.

If the breather on the rocker cover was not checked it would allow unmetered air to enter the crankcase and be drawn into the supercharger. The check valve in the breather stops air in but relieves excess crankcase pressure if any.

You can run an unchecked breather if you want and tune accordingly. I routed the lines the way slp recommended.
