Turbo oil drain problems w/AAM kit

zguynate

The drivers side turbo uses a 45 degree fitting for the oil drain, and due to the starter has to be angled somewhat away from the motor. So the line has to curve back to the motor and then somewhat levels out. I've tried to see if I could change the routing of the line to make it better but due to the close proximity of the oil pan to the subframe, the line will always rest on the subframe. It's driving me crazy.

I've done a compression test and all of my compression rates are very good. I'm going to see if I can borrow a leak down tester also to make sure. When I got tuned I was having an issue with the dipstick blowing out... that's why I removed the AAM pcv setup. I haven't had any issues since I removed them. Before I could drive the car and when I parked it and turned it off, I could hear burbling from the motor. When I pulled the dipstick I would hear a rush of air. That has been alleviated but I'm still going to see if for some reason I'm getting leakage through the cylinders causing the line not to drain properly. I'm pretty certain I don't have any issues... but I'm unsure what to do next. I would like to avoid having to do a scavenge pump because I like simplicity.

I did talk to AAM and they said that according to Borg Warner, it's almost impossible for the turbo seals to go bad due to the design. Something about the seals being similar to a piston ring. They suggested that I clean it out and try it again. That didn't work for me obviously lol.
