Suggestion for those who want to avoid trouble with the oil return line: go to your local parts store and get a foot of the same size tubing.
Cut off a section that's maybe 1.5-2" longer than the stock return hose. Stick that puppy on in place of the stock piece, it'll go farther up the hard line on the turbo and farther down the hard line on the block.
I couldn't get the stock piece back on right for the life of me. Longer hose was so simple and effective that I wish someone had told me to do it to begin with. So I'm telling you guys.
