I have also noticed increased oil consumption. I recently replace my OFHG awhen my alternator failed and the thing stumbled like crazy after start up and had a noticeable whistle. Perhaps even before that but certainly for the next 15-20 startups it seemed like it almost wanted to die when starting. That has since gone away. I remembered this issue and checked today and it is sucking a decent amount of air through the oil fill. I am also hoping that this takes care of an odd sort of engine flutter i have at the mid range rpm's in second gear.

I am looking at ES 1905414 and ES#: 24265. Geneuine BMW kits sold by ECS tuning - CCV and hose kit and the second is the cold climate dipstick. total with tax and shipping is 307. Is that par for the course? I like ecs tuning and they are close by so I am a bit partial.

Sounds about right for price. I would budget another $200 for preventative maintenance pieces while your in there since you're chasing an issue that could be a few things. As far as your symptoms go, a vacuum leak will cause the whistle and strange engine issues. Since the CCV is quite burried, you will be able to take off a lot of parts that need to be inspected/ replaced. Key points I've always done are TB gasket, idle control valve cleaning and now gasket, clean out the CCV "manifold" that distributes vacuum to each IM runner, inspect/ replace those gaskets, check all intake boots for tears especially in the flexible grooves, check the vac lines that connect to the intake boot (post MAF), clean MAF, check the DISA valve for condition, reseal DISA with silicone... I think that's it. Budget a weekend to do this and do it in a heated garage of possible. If you can afford to be without the car, tear down and inspect parts, then order. If you can afford to replace/ hold on to extra parts, order everything and go to town.

All of these things are identical to the e46 assuming you have a 3.0. Check e46fanatics.com for how tos on these subjects if you get lost!

mcurcio, thats about par for the course - the cold weather CCV and hoses is about $150 or so - the updated cold weather matching dipstick guide tube is $150 in and of itself (but worth it as its a superior design IMO)

How did you like the Vanos rebuild? Did you notice any changes?
