Turbo oil feed

The hard line on my turbo cracked and sprung a leak a few weeks ago, so I went and got a new one and that has now cracked and started leaking. Im angry. I am going to replace the hardlines with braided lines and I wanted to know if there is a restricter built into the lines? Does anybody have any experience with this? I looked up the parts I needed from this site. but the links no longer work.

My FC is my only car and I have to overnight parts from summit. the sooner the help the better.

Thank you

for the journal bearing turbos, you don't need a restrictor. What is causing the line to crack? Are you talking about the at the side of the banjo, the 2 bolt flange, or the flared fitting between the 2? Make sure your using a line wrench for the flared fitting part that joins the 2

Its the short hard line at the turbo flange mount. It leaks oil right onto the turbo. It may be leaking because the longer hardline isnt perfectly aligned t the flared part but its only off a few millimeters (literally) not enough to induce a stress crack after a few weeks.

I know 6an is too big but its the easiest way to do this setup.

Well, no one had any answers so I just figured it out myself.

I used 4AN fittings and hoses. The only problem I had was that the 6AN to 4AN reducer made the fitting sit to high. I had to route the hose out and around. Luckily I cut the hose longer than I needed. I would also use 2 90 degree fittings instead of the 45 degree fitting.

Nice job!

In the future, what you could do is leave the 2 hard lines threaded but not tightened, tighten down the banjo and then the 2 bolt flange, and then tighten the flared parts at the very end to make sure its all clocker properly

Good job. That's the good thing about making your own lines. You can route them where you want and change it up later on down the road. If I would have caught this thread I would have helped, but looks like you figured everything out.

Yeah my biggest concern was the turbo flange. It's hard to tell whether or not it is a universal part. I just rolled the dice and got it. I really didn't have any other choice but to try. But it seems like turbo oil feed flanges are for the most part universal.
