View Full Version : Oil return and coolant routing....

04-22-2012, 01:17 PM
I just finished installing my oil return and coolant supply? lines from the turbo to the block on an AEB. I went by the list that PSI Concepts had up for their oil and coolant lines, but picked everything up from a local race shop. Before I tightened everything up, I just wanted to see if there were any problems as how theyre routed. Pics below.....

Oil Return



Coolant Supply?


Both lines in the shot

You need to cut that oil drain line shorter, and have it go from a straight line back to the pan. The 90* fitting off the oil pan adapter should be pointing straight up, with the line going in a straight line (or an much as possible) to the oil drain port on the turbo. Coolant line is just fine the way it is.

Alright. I just wanted to get others opinions before I tightened everything up. Kind of wish I would have picked up a 45* instead of the 90*, but Ill use what I got. I was hoping to have it all done and ready roll by today, but Ill plan on next weekend.

90* is the one you should use. But you want the oil to be able to drain out of that line, which is why you need it as straight as possible (does not have to be perfectly straight). If not, the oil will accumulate and puddle in the line all the way back to the turbo.

Sounds good. Thanks. Ill try and get it as straight as possible then.

if you wanna clean up your coolant return, pick up a fitting like i did. my coolant return is -6, so i got a 14mm x1.5 to -6an fitting. cleaned it up nicely and no stupid barbs to deal with. as for leakage, it isnt installed yet but im put thread sealent on so it should hold fine.

Is yours an AEB? Mine has the barbed port coming off the block, its not threaded.

oops. i had no idea aeb's had a barb fitting in the block. are you sure you can't thread it out? mine is 06a block and a banjo bolt is supposed to go in there.

Yea thats what confused me when I was looking through PSI Concepts list of parts.
