So went ahead and plunged with a catch can arrangement. My guy used a Moroso 84565 CC. He made some custom braided hose and T'd into the bottom oil return line from the turbo. Now the oil returns back to the oil pan. Works great
He also cut about a 1/3 from the check valve spring and added a different O ring. Seems to open better which we thought could be contributing to the boost push of oil. Boost before was coming in about 27-2800 rpm. Now it's coming on around 2200. Feels a load better. I picked up an extra 2mpg on my usual highway route. To early to tell if this was isolated but jeep runs great.
