Maybe this is the 7afte blue smoke solution Options

[Conwa]

Hey,

I've seen alot of guys over here that have build the 7afte.
I'm in the progress of doing it now but when i look at most of the 7afte's
the oil return line is positioned in the oil pan.
Alot of 7afte's have the problem of blue smoke when full accelerating.
I think thats caused because the oil thats returning dont flow free into the oil pan.
Because its already filled with oil, it will eventually go there but not how its supposed to do.
Thats why some oil stays in the turbo and creates blue smoke.


I drilled a hole above the oil pan so its flowing free.
Cant make it quite clearer (im dutch, english is not my best language)

Maybe im wrong but we will see that on sunday (then its running)

You are right at some point. I thought about this as i had my 7AFTE smoking like crazy... You drilled the hole in the cast piece witch is over the oil pan, right? Then i was buidling martin's 7AFTE i drilled the oil pan, cuz i aint wanted to risk drilling the cast piece, and i saw no smooking problems with his setup. Ussualy this might happen (the smoke under the WOT) cuz of the weared out oil seals in the turbo..

i had the blue smoke trouble to but i drilled out the cast above the pan and ran a 1/2" return line with the reducer and i dont smoke any more even at wot and full boost but i also have a rebuilt turbo also not a used one.

Mine is at the oil pan and doesn't smoke. It used to smoke because it had a broken piston. My oil return line is straight down. But you're right...if it's not perfect, meaning that it Js on the bottom, it'll puddle and choke the turbo. It cannot go down and then up into the fitting, so the oil doesn't stay there.
