Something about Turbo..?

Sup guys, one of my relative has a sr20det motor in his 95 240sx. When he put in the S15 Turbo, he drove it for a while. Okay, here's the Turbo part that mite make a little, but no sense at all. Okay, he told me that his car has oil leaking from under the engine?. He also said it mite be a wire or piping thats causing it to oil leak?? Something that regulates oil from the engine to the turbo...? weird? It was something like Turbo Oil Regulator....? wtf? i have NEVER heard of something like this in ANY turbocharged car. My bro said it too. It mite be the turbo leaking from oil...but wait, if the turbo was leaking oil, the car is undrivable...rite? well, the issue here is that the 240sx with the SR motor is leaking, and not from the turbo. My bro told me the car is leaking because of a wire or pipe that cracked, causing oil to leak, but its near or connected to the turbo.? confusing, but can you guys lead this thread somewhere, because i do not know where to put it. Sorry if any confusion, i just wanna know anything about how turbo leaks and possible ways oil can leak to the turbo in any turbo car. thanks!

If oil is leaking externally from the turbo area, chances are it's either the oil feed line or the oil return line. My bet is on the feed line since there is a lot of oil pressure flowing through that bitch. The oil in the oil return line just kinda slowly runs down into the pan.

How can you fix that? Or do i have to go a Nissan 240sx Forum to find how fix it?

It depends on why it's leaking. If it's just oil leaking past the threads on the fittings, then it's just a simple matter of taking off the fittings, applying Loc-Tite (thread sealer) to the threads, and then torque it all down nice and tight.

If there's a break or something in the actual line, then you could either A. Get a new line or B. Seal it up with some sort of compound (this could be risky though, and I'd suggest getting a new line first).

How much oil is it leaking? Oil return lines are notorious for always having a very small leak. The gaskets they come with are seldom good enough for a clean seal. If it is a more serious leak, Matt's suggestion about the oil feed line is a good one.

I've never heard of a turbo oil feed regulator :/

hahahahaha...same here. Well, we dont know yet, because its so cold up here in minnesota. well, if i remember, its a small oil leak probably coming from the oil feed line, because i cant think of anything else..........except for the "turbo oil regulator"...lmao...
