smaller return line?
 

i've got some friends at work who say that if i use a smaller return line the pressure going back to the oil pan will increase.

FYI: i'm running the cheapturbolines.com kit i have no idea what size the feed is (maybe -4) but the return is 1/2 inch opening.

this question has come up due to my turbo blowing from a rise in my return line (never trust anyone to do anything to your car :( ) so i'm wondering if a smaller hose would help.

BTW: i fixed the rise in the hose.

No, no. There isn't any pressure in the return, so you want the biggest drain possible. 1/2" is the smallest I would ever go.

I believe they use a -3 with a -10 (1/2") drain.

thanks, so i'm eliminating a lot of things which could of cuased this incident. i've pretty much nailed it on the return line. hopefully when it gets running again i'll know for sure.

My return line has a slight dip in it and I'm not smoking at all. A -3 feed is small enough that it's not feeding to much oil pressure to the turbo. To make sure just get a cheapo oil pressure gauge. I'm thinking your turbo might have seen better days before you even got it. :P

Your post didn't make a lot of sense to me.

What do you mean by your return line rising?? Creating pressure in your oil pan??

Not being a dick, but you need to clear it up and we can tell you more.

by rise i meant it dipped below the hole in the oil pan before coming back up to meet it. i just had to shorten the return line and now thats fixed.
