Is there better n54 turbo oil drain lines that provide a better/quicker oil flow. I'm aware RB makes them, but I was wondering if someone else has put such a product together.
I'm aware of these from RB, I was just wondering is someone else ventured into making something similar that would see just sell for the front turbo. The front turbo drain line is the problematic drain design. I have see twice when the front turbo drain was replaced with another unit or a new unit and smoking actually diminished. If you have smoking on the driver side tailpipe and your exhaust setup is designed so that NO "X" or "H" pipe is present, the problem is likely to be the front turbo oil drain.
