First off, i would like to say hi to everyone on this forum.

Okay, my problem is, i have had 2 different turbos on my car, i bought them used, and the owners said they worked correctly.I was just reading another thread about oil pressure causing the turbo to leak/smoke.... I dont believe i have a buildup inside my turbo, all the lines are straight, or bent with NO kinks. The Oil feed is the normal size ( i picked it up at a local shop, he said it was turbo lines, which is steel braided) .. The oil return is on top of the pan, not on very top, but close to it... The oil return line isnt too big, kinda small in a way. Could this be causing it to spill out both sides of the turbo? It leaks out the hot and cold sides of the turbo.. . I bought a brand new turbo because im thinking it was just the turbo that was fucked up.... But any comments/ thoughts will help.. BTW, this is on a 00' B16a2.

Thanks!

 

here is a pic of the oil return line.. Sorry for the shitty pic

 

Im guessing you dont have a oil pressure gauge?

Im gonna guess youre running a -4 line and with the 80+ psi B series like to put out and with such a large feed line and your small (thinner than the feed?) Id say some oil is definetely being forced past the seals.

Theres quite a few ways to solve this, would help if you knew exactly what you had

 

this is on a t3 turbo btw

 

holy christ that oil return is small? what is that 3/8ths? You need to get a large oil return, nothing smaller than 1/2in

Common size returns are 5/8 - 3/4

No wonder your pissing oil everywhere!

 

here is the oil return and feed lines


Im gunna go buy a 1/2 line tomorrow probably...
Im not boosted yet due to it leaking. but i know my problem now, so im gunna be boosted again this weekend!! thanks for the help guys.. really appriciate it. Anyone have pics of their oil return line on their car??

 

Well your gonna need to replace the fitting in the pan too! like I said, atleast 1/2in

here are a few pics



The fitting on the pan



The fitting on the turbo (you can get these at tunertoys.com)



And the return, its a nice smooth return, the hose is preshaped.. found it at the junkyard off some heaterhose.







You get the idea, there are more in the TURBO PROJECTS section,

thanks guys! u think this will fix my problem? So i should go with 1/2 hose and fittings?

 

Yes and Yes

maybe 5/8ths.. like I said big as possible

 

also i hear some people saying they use a oil restrictor.. What do these look like and where could i pick one up from? Any one got pics?
