Don't tell me to search, I did. Plus I'll do mean things to you

So the friggin oil feed line to my S14 turbo is leaking pretty badly. Unfortunatly, it's not leaking at the block, but at the turbo. I can't tell if it's coming from the threads or up through the line in the middle of the bolt. I'm using the stock CA oil feed line and the drain line is unrestricted, so It's not that. I'm not burning any oil or anything, but this leak is ticking me off. Any idea's anybody?

I'm running stock lines with no problems on my s14 turbo. I used teflon thread sealer on all the fittings before I put it together though, and I run 20w50 oil.

This is the only thing that I didn't do, but since the oil feed is an inverted flare, the threads aren't doing the sealing, so they shouldn't need teflon. I can give it a try though...

The copper washers are for the coolant lines, not the oil lines.

Cuz I'm retarded. I wish I had now. Actually when I was installing all of that, it was on an engine stand and so it was easy to do. I didn't think I'd have to pull any of it back off anytime soon, so I said forget it. Ofcourse I'm eating my words now...

if you're using the flared type line you should change it ASAP. Nissan upgraded the feed pipe around '92 because the early style one caused starvation to the turbo. the later one is a banjo fitting, you should get one of these or for ease of fitting a braided flexible line

I haven't had any problems running the stock line on the S14 turbo, but I did have the same problem with my brake lines (same style fitting) I cleaned everything with brake cleaner and made sure the fitting was really snug and I haven't had any problems.my $.02

Well imagine that, I just learned something new!!! I guess I'll have to bust for some Taka lines. Grrrr. Those damn things are such a pain in the arse...
