Should I replace these power steering lines?

Should I replace these power steering lines? They don't appear to be leaking enough to drip. Car has 67k miles on it.

I wouldn't bother. The OEM part by Rein seems to leak earlier than OE, though OE will leak at some point. Yours looks ok.

I wouldn't replace with OEM...I went with the Chase Bays full kit. It's a bit more than OEM, but I believe it should be much better long term.

How do you like the chase bays kit

How do you like the chase bays kit

I'm still sorting it out a bit. Partly on me. Partly on them, maybe. I'll first say that I'm 100% a fan of the company as their customer service has been VERY good.

After my first track day (car is track only, trailered) I had some leaking. Turns out I didn't tighten the banjo bolt fully. However I was seeing some seeping out the cap, which is one of the things this system is supposed to eliminate. I contacted CB and it turned out that since I ordered it, they discovered a potential issue with the banjo bolts not being restricted enough (to match OEM setup) and also another restriction point in the high pressure hose. So, the seeping is likely due to aeration...could have been from me not tightening it enough. Could have been from the lack of adequate restriction. Anyways, I'm happy with it and when the parts arrive Friday, I'll get it all back together...the following weekend I'll be on track to test it again.

Long answer, I know, but I'd say I'm happy with it, if not for any other reason than I know CB will work with me until I am happy with it (should anything else come up).

Replace it.

REIN seems to be the OE manufacturer of BMW PS lines according to FCP:

If i had to do it I wouldnt mind doing REIN.

If it’s not leaking then no. But those are prone to leaking prematurely. Mine leaked at 160k miles. Replaced with...oe I should’ve gone with aftermarket

Replace with OE. Don't bother with aftermarket such as chase bays. I tried it, had a bunch of issues and went back to stock. Running good ever since. Its amazing why they would bring a system into the market that has less capacity than stock, hence causing high temps.

Aftermarket does not automatically mean better.
