BTW - what type of oil are you using?

For my money, for the CCV, I would buy this -

Jeezus H Roosevelt! That thing is beautiful. Just read all about it. I'd keep my engine cover untrimmed though. Glad that's an option. The biggest drawback for me would be the clean-out but I guess that's with any catch can system really. Also, the price :yikes: Plus I'd probably need to buy the cold weather dipstick. Not sure what I have now. But I like the fact somebody has put this much thought into it! Those guys need to fab a tool to change tension strut bushings on-car. I'd be all over that!

Went ahead and bit the bullet and replaced the oil separator. Boy, what a task that was. I couldn't find any great documentation about the procedure (I'm sure someone will link to what I looked for now that I've finished it :) ) so it was a lot of trying to figure out what comes off next and trying things. The oil drain hose that goes back to the dipstick filler hose was soft and pliable. I grabbed it and was able to pinch it off with my fingers. I've never seen rubber turn into whatever that had turned into.

Toughest part of the job was trying to figure out what was stopping the manifold from coming off. Turns out it was a large nut (17 or 19mm) holding a bracket to the block under the throttle body. Once I figured that out, it came off easy. I went ahead and took off the fuel rail. Just seemed easier than trying to fight the connections in the back.

If I had to do it over, it would go pretty fast now, but it was a long day. Probably had about 6 hours in it total. I could probably do it in half that if I had to do it again.

It needed to be done for certain. Time will tell if it fixed the issue.

One odd thing I noted. I took off the plastic pan under the front because nothing irritates me more than dropping things and having them go into never never land on the plastic pan. When I did that, I noticed a lot of oil residue all over the roll bar looking part of the frame, right at the front of where the metal pan is bolted. When I looked up at the engine and all around that area, it was all really clean. Not one sign of oil or a leak anywhere on the front, but that bar wasl covered in built-up oil residue. I didn't quite understand what was going on there, but I was happy to see that I couldn't see any signs of any oil leaks on the front of the engine or once the manifold was off, on the driver's side of the engine. It was all actually pretty darn clean.

I'll report back once I get some miles on it to see if it resolved the issue of my disappearing oil.

lots of youtube on the CCV replacement.

I wouldn't be surprised if the residue you saw was power steering fluid. it's possibly leaking at the bottom of the reservoir and running down the hose to the steering box. Cheap and easy fix.

and DITTO on the bits in the pan, lol! I find stuff down there every time I take it off!

For my 2006 X5 M54 with 115K. The stock CCV (I wrote a DIY in forum) was a waste of time and money.

The CCV Mod was the ticket, oil consumption problem was solved.

Yeah, I saw that video. I wanted to take the intake off, not try to work under it. It looks like his didn't have the cold weather kit on it. With the cold weather kit, you almost have to beat the thing in with a dead blow hammer to get it to get it into position and the cold weather insulation on it seems a little thick around the outlet tubes so I couldn't get any of the hoses to snap into place without trimming a little away around the outlet tubes. I would have been in a mental institution if I had tried to get those hoses on while still on the car.

One thing that really impressed me was seeing the tops of the valves when I took the intake off. They looked fantastic. Not one of them had any carbon built up on them. They almost looked like new. That gave me some comfort about my engine in general.

On an interesting tangent, we're all complaining about the oil usage on our e53's, I'm looking at some 7 Series cars and found a thread about BMW losing a class action lawsuit for the excessive consumption on their 7 Series V-8 engines. You have to take you car in and they start the process of monitoring your oil usage. Once you hit a certain number of miles, they look at it again. If it falls in the range of the lawsuit, then they'll replace your entire engine. Only issue is that you have to pay for a percentage of it. Cars with about 100,000 miles seem to have to pay about 40% of the bill, which is working out to be about $6,000.

The oil usage seems to be about 1 qt for every 1000 miles and that qualifies for the engine replacement. Seems like this isn't limited to the e53 3.0 engines we have in our X5's.

Bavauto has a very good video on the CCV parts replacement on the M54. It made the job a lot easier on my 3.0. I also did the valve cover gasket at the same time and that greatly reduced the oil consumption.
