The motor is a stock SR20DET Redtop it appears it's leaking oil from feed on the turbo. More specifically it looks like the crushed copper washer that sits against the turbo side of the banjo has failed.

Will replacing the crushed copper washers stop this leak? or is there something else going on that I'm unaware of? There is no shaft play, no oil in the intake side or exhaust side of the turbo, and no smoke or noise.

I've been thinking about replacing the oil and coolant lines with steel braided hoses.

What's the difference between these two sets of oil lines? They both say replacement for OE lines.

I'd try replacing the copper washers first (2 should be less than $1). I doubt anyone would know if anything else was going on considering we know absolutely nothing about the history of your stock setup. But generally, a leak where a copper washer is just requires replacing the copper washer.

Your links show one "bottom mount" replacement lines & one "top mount" replacement lines. Stock SR setup = bottom mount.

they're copper washers, nothing special. You can get them anywhere. Just take out your current one & even bring the bolt - go to hardware store, home depot, whatever. Match it up, you're good to go.
