It realistically took about 3 and 1/2 hours start to finish so not too bad.

Why don't you read the whole thread. If you can't follow it, don't DIY. This is one of the toughest DIYs. The only shortcut is not removing the intake but it is still a major PITA. It actually took me longer to install the new CCV and pipes then taking everything apart.

PITA = Pain In The Ass

The Valve cover hose is step #19 in the DIY so you need to do step 1-18 to get to it. Get it towed if you can't follow the steps. This is an ADVANCED DIY .

Allocate at least 5 - 7 hours of work depending on your level of mechanical proficiency.

BTW. By the time you get everything apart, you may as well replace everything, CCV and four associated hoses. If you READ the threads, everybody who has done this recommends it. Not only did the hoses break apart when I removed them, the old CCV broke in half too when I was trying to move it around.

I just had this done at an indy shop. Cost me 5 Bens . They changed the PCV unit and the 5 hoses connected to it. I run it a month and see if oil consumption is less.

That is not a horrible price. I've seen it as high as $1200. Still sucks when you consider the parts cost less than $150 and it takes about 3 hours max.

I use a local place that specializes in BMW stuff. BUT, a friend just bought the oil separator, all 5 hoses, and a valve cover gasket for $122 SHIPPED from Tischer BMW. Apparently they are running a special through year end and have free shipping! COOL!

OK, so I owe so much back to this forum, so I thought I'd try to pay some of that back. I've finished my CVV replacement job which alltogether was a MAJOR BI%^$! Also did the Valve Cover Gasket. CVV replacement is truly around 7-8 as someone said before (with 1 being an oil change and 10 head gasket replacement). Mostly due to the lack of space to put your hands / fingers in anywhere. Took me about 7-8 hours - as I usually go slow if I want to drive the car again LOL, and about 2 hrs for the Valve Cover G. I started the car today and all sounds perfect! Knock on wood. Couldn't drive the car yet as my driveway is blocked, but had it running for 20-30 minutes and warmed it up to normal operating temp. All good so far. Test drive tomorrow.

Here is my vid on the Cold Climate Oil Separator.

If I could offer any hints on the procedure based on my experience...

I'd move step 9 (dipstick tube) to right before current step 13. You'll want to have as much room for removing the tube so that you can grab onto it tight.

Same for re-installation, keep it in 13. It was a major b#$% for me to put it back in. Tried for almost an hour and it wouldn't go in, had to hammer it down at last, and then went easy all the way down, but AGAIN - you'll want to have as much room for this, so do it before DISA and lower intake boot.

Just my 5 cents. Good luck to all.

SO all a cold weather separator has is an "overcoat"? What a ripoff. Looks we know who designed the oil separator. I can see it know, the heads of BMW went to the window regulator department and said "Ned, we need you to make us a PCV valve, nothing complicated ok." Ned replies "my record speaks for itself, I'll take care of it". 5 hoses and 4 months later, the most complicated PCV valve ever conceived was placed on our E46's.

"well done Ned" said the execs. "That will generate some revenue one day"

My thoughts, exactly, especially after reading all the horror stories. And if this is what they did in the "old" E46 platform, I tremble to think what they cooked up on the E90.

I'll have to baby the 325 until the E180 platform comes out in a decade or so...

Great analogy....leave it to BMW to take a (should be) simple device like a PCV and turn it into something so diabolically fiendish that even other Germans scratch their heads when they look at it....

Yep, that's all it is. I'm in toronto too and ordered the cold weather one too but discovered the car only came with the regular one.

Without removing the intake, I found it impossible to install the cold weather one. Ended up ripping the jacket off and installing it without it. Luckily I only paid $10 extra for the cold weather version.

I wondered about that....

Seems like you could just take the normal one and wrap it in header wrap or use some thermo-coating spray and get the same result.

Really??? I put mine in - the complete set w/ cold weather hoses (total of ~250 bucks!). It was a true bi$%#, not even the separator itself, but the f$%^& hose that goes up to the fuel intake area (not the one going to the valve cover). The thin vacum hose was another b%^& as it was too short after I ripped it off the old separator, but I managed. The sep. itself, with the cold weather coat took me 10 minutes to put in, and that damn uppermost hose about 2 hours... You have to twist it to the left to be able to push it in and then right to lock it... OMG this almost broke me, I was about to give up... LOL The author of the DIY recommended studying the mechanics of the hose connections before putting it all in - I think this was an extremely great advice, since to hook up that hose, you basically have to work blind folded with only two fingers to use...
