N62 oil catch can.
 

Hey guys here's a link to a 545i with oil catch cans installed. Seems to have fixed his cars smoking problem.

545i Dual Catch Can setup with pics - 5Series.net - Forums

interesting writeup.... I wonder if he tried to change out his valve cover gaskets before adding the cans?

I have seriously considered doing the valve cover gaskets, but I have NO leaks and would hate to have them after :(

if it ain't broken - don't fix it!!!!;)

Agreed!

But if it's broke from the factory, it's up to us to fix it correctly :)

Now we just need to figure out how to incorporate a single catch can that will drain back into the oil sump when we turn off the motor... now that would be slick!

Sadly cant see his pictures

I think he stated that he changed his valve cover gaskets about a year ago. I'm kinda with you...why not fix the vacuum leak first. But then again the oil catch can seems to be the quick fix.

This recent thread discusses a catch can.

I will actually be trying this,

@ person above, you have to make an acc to see pics there,

Parts cost $33, ordered them a few days ago should be here soon, hopefully works, will make a thread after i install.

Let us know how it goes. You might wanna try this as well.

Oil consumption ? remedy ? - BMW E60 5-Series Forum | 5Post.com

A fix for Oil consumption problems

Investigation of Oil Consumption Issues should begin with the CCV / Intake system. Oil in the intake should not be considered normal and reduced to as minimal amount as possible. Oil that is sucked thru the intake will cause carbon build up on the intake/exhaust valves and the pistons. This will also contribute to catalytic failure and have an effect on engine performance.

My car: 2006 BMW 550I V8 N62TU - 94,500 miles
(No external leaks)
After I replaced the CCVs, It smoked and would not pass Smog Inspection. These issues were fixed with a carbon cleaning chemical regiment (Sea Foam). But it continued to use a quart + of oil every 2>3 tanks of fuel. (Everyone had previously said that this was normal for a BMW) After my modification to the crankcase vent system - It may have used - maybe (it's hard to tell) less then a pint after 2>3 tanks full of fuel.

My Fix: (about 1 hour)
Parts needed; 1 - Scotch Brite (3M) pad #7447
2- Stainless steel garden hose screens
(mine had o-ring attached)
-Cut 4 pieces of Scotch pad approx. 1.75 X 1.75 inches.
-Trim rubber washer attached to the hose screen so it fits snug within the valve cover vent tube.
- With CCV diaphragms removed, fold over 1 piece of pad and insert within the slot of the inlet vent port. Be sure pad is pushed low enough so it will not interfere with the diaphragm when reinstalled, but firm enough to stay in place. Reassemble and repeat on opposite valve cover. This is a pre-filter to prevent oil from CCV.
-With vent tube removed (valve covers to intake), fold over 1 piece of pad and insert within valve cover vent outlet nipple. (It may be necessary to trim some length of pad for vent tube reinstallation) Insert screen above pad - this keeps pad from being sucked into the intake manifold. Repeat on opposite valve over and carefully snap vent tube in place. This is a after CCV filter to stop any oil that may have made it past the pre-filter.
-Top off engine oil and keep track of progress.
- I will continue a carbon cleaning regiment at least every 10,000 miles.

Note; This Scotch Brite pad #7447 is about 1/4 in. thick - a thicker pad can be used as available - just compensate for this change.
