My CVV (Oil Separator) DIY Journey in Pictures

I replaced mine preventetively before it started leaking oil (one of the symptoms). Leaking unit can be the cause of increased oil consumption.

In my case I started using oil more frequently and also had the "walrus sound". I can tell a difference in performance from the replacement.

Great DIY. I'm replacing mine when it gets warmer. Did you get all the parts from Plaza? I live here in MO. I know they give you a CCA discount.

Oh, no. Plaza is good (they say) for service, but it's the most expensive dealership in town too...I live 5 minutes from Plaza and buy parts there only in a pinch.

I bought mine from Tisher (www.getbmwparts.com) - $150 for a complete set including all hoses

I had the occasional "Dead Frog" groan and over 100k miles so I bought the parts last month. Today I had my Indy shop (Valley Motorwerks in the Sacramento area) install the new parts for only 2.1 labor hours. A good deal if you ask me considering I was expecting over 4 hrs based on other's estimates.

Yeah I've gotten parts from Tischer and they are cheaper. I've gotten parts from Plaza and they matched the parts from Tischer. Now I dont know if it's just me because I get parts there all the time. But they are closer and I dont have to wait for shipping. But then again some of the parts from Tischer has free shipping. I'm going to end up doing this DIY but it's going to have to wait till it gets warmer.

I never noticed others from StL here. Good too see people from back home. I grew up in Arnold. I miss the weather. (mostly the storms, these people up here don't know what a thunderstorm is, a flash of lightning makes it a storm, HA!)

When you pulled out your DISA, I noticed the inside is clean, there are no tiny white granules (like sand). When I did this CVV job, I have to extract and clean as far as I can reach inside. I think it is because I have a K&N filter which I tossed out and went back to OEM. Remarkable write up!

I have read some really great DIY instructions but I have to say this...man, this is the best one I have read and the pics are outstanding...Move to the head of the class!!!

I went to the Tisher site and couldn't locate the CVV. I put CVV and then oil separator in the search engine and turned up no hits. How do I locate the CVV?
Thanks

11617501566 PCV Valve; Pressure Regulating Valve/Oil Separator

Of course that is for my 02 325i off AutohausAZ... $54

Awesome DIY . I love how the instructions are integrated into the pics.

This was excellent. I took my time and it went very smooth.
Thank you!!

Very nice job! Im going to start my maintenance when spring rolls around like flushing all the fluids, my own inspection 1 and 2 and a clutch (which I am going to try a write up on). Im at 113k and clutch has never been changed.

Excellent DIY, but I am afraid that it's too complicated for me to do it myself.

I am pretty sure I will break something in the process or forget to put things back in the right order. LOL.

I will take my car to my indy and pay him to get it done if mine is indeed broken. Thanks for the excellent effort though.

Alex, so the needed parts are the CVV, vent pipe, connecting line, vent hose, the return pipe and the dipstick housing, right? Do I need any o-rings, etc?

Jake, if you buy the kit from Tisher it will contain everything you need ($150) and it's cheaper then buying parts separetely. The only additional thing I bought was the lower intake boot, PN 13541435627. You can also buy a throttle housing gasket in addition, PN 11611716174. I just reused mine.

If you do decide to buy everything separately this is the parts list from Lbert's diy:

These are included in Tisher's kit:

11617501566 Oil Separator
11611432559 Oil Separator Hose to Valve Cover
11157532629 Oil Separator Oil Dip Stick hose
11617504535 Oil Separator Connecting Hose
11617504536 Return Pipe from Connecting Hose
11431740045 O-Ring Oil Dip Stick Tube to Oil Pan

Additional:
11611716174 Throttle Housing Gasket
13541435627 Air Intake Boot; Lower

Good luck!

Danke

Would a gunky buildup in the engine oil filler neck and dip stick be indicitive of a problem with this part? Changed oil (fully synthetic Mobil 1) less than 6K ago and began to get engine oil level notices and some noticeable power loss. Tried whiping the **** out and running 1 quart of new oil and oil treatment bottle through and 1 week later crap is back and only a matter of time before back to low. See no obvious leaks or anything.

A small amount of " BMW Mayo" under the filler cap & dipstick is normal....these are the highest points in the system, where oil residue mixes with condensation and forms the mayo.
Any BMW that uses a quart of oil in 6,000 miles cannot be criticized....that`s pretty damn good, all things considered....

Okay, I will keep that in mind. Any credibility to the Positive Crankcase Ventilation System being recommended to replace every 30-30k miles, part is supposedly about $60. My X5 is close to 90k and it has never been replaced. Is this related to the milky white or am I getting distracted by information overload on the net?

Alright so is Tisher a user on Bimmerfest or a parts supplier? I am having a hell of a time getting all the parts and I refuse to go to the dealer so a kit is very attractive right now, does this include everything for the CCV as well as the Oil separator system?
