Oil Seperator

Hi guys I'm about to order a replacement oil seperator. I was wondering if there was a recommended one I should use. I'm on a budget right now and I'm considering this $40 one on Amazon

There's no link. Haven't dealt with mine yet but it is a PITA to replace, get all the hoses and O-rings because something is bound to break. This one is kind of elaborate but complete. https://www.fcpeuro.com/products/bmw...11617501566kt2 This is the separator by itself with a video on how to do it. https://www.fcpeuro.com/products/bmw...ve-11617501566

Hopefully the link will show up now, it's a koolman. There's this video on YouTube by the 50's kid who just takes the whole intake manifold out which I'm probably going to do

Here you go IMO follow this DIY by 50skid and replace all plastic and rubber that you can while changing out your CCV.

Dont forget your hard plastic coolant pipes and the kit you post should be ok.

If you take the manifold off there are a few things that should be done while it's off. The hard plastic heater lines for one, all the vacuum lines and even the starter, but that can be done with it on. You might want to consider new intake gaskets.

I don't know about Koolman. As time consuming and tedious as the kit is to Install, I'd go with a known quality mfg. It's hard enough to get everything reattached correctly so you don't throw any more codes, now you're adding a quality issue into the mix.
If you are going to sell the car just go with it and see, if keeping it, the fcpeuro.com option with a lifetime warranty is the way to go.

dont forget to check out ecstuning.com too.. plus pull your hose that is connected to the valve cover(black plastic one) and see how it looks inside, if its clean you could get away with just doing the separator although i recommend doing it all while there and you dont need to remove intake manifold but its your call. my .02

Brand: Koolman? You'll quickly learn some parts on these cars should be replaced with genuine-only. This is one of them.

be careful with those cheap ones. I installed one i bought for 50 dollars and it failed within a few weeks. I ended up replacing one with a OEM one and when I was wondering why it failed so fast I cut it up and found the cheap one was missing a spring at the diaphragm and it soon filled up with oil. Go with a quality part because just to get to the part and replace all those tubes and seperator is not fun and is a huge PIA.

Also replacing those parts, depending on where you live, for me I live where it gets pretty cold in the winter, make sure you get the insulated hoses or you'll be changing them sooner then you want due to condensation. I just went through this process.
Good luck.

This kit that jmo69 linked is the one to get and only $121. All OE parts (high quality) and a complete set. Don't put any cheap Chinese junk parts on your car. They may look similar to the quality OEM parts, but they are total crap. Spend just a few dollars more and get the good stuff that works correctly and lasts a long time. The CCV job is enough of a pain that it's totally worth it to get the quality parts.
