I can vouch with direct experience that this plug does not work/fit. I tried on Friday and it's too small.

Hi all,
Been reading heavily on this issue and have begun converting my X5/E53/M54 to this mod(utilizing BOTH AD intake ports) due to a problem with vehicle that arose recently, which I believe is CCV related(X has 189,996 on ODO). My daughter(on one of our practice training drives) was stopped at a light to make a right turn into a shopping center, when started getting extreme smoking from exhaust pipes. pulled over immediately and turned it off. I popped the hood and looked around for any visible issues(saw nothing). Let it sit for a few mins to get oil drained to get accurate reading(was on level ground). Checked oil and it was LOW. Opened up filler cap and it was mildly smoking(didn't notice suction amount nor observe any hissing). Let it cool down a bit, then added a full quart to it til it registered on dip. There was no "Mayo" or anything on cap/in oil(it looked normal and ok). Checked coolant and it is topped up, with no visible oil or contaminants in it. Started it up and drove across parking lot. Upon start, no smoke, but began smoking very soon after driving across lot. Parked it in shade(I live in Vegas) and called for AAA and ride home. I have it here in my driveway and have been investigating to see what dealio is. I have not done a compression/smoke/leakdown test. I'm going to hook up mod and fire it up to see what result is. I assume, from reading, that residual oil all over inside- see pics -will cause continued smoke for some time after issue(if CCV) was resolved. The smoke appeared to be white to me, but who knows since it was quick before I shut it down and was behind wheel and in the shade for 2nd time, crossing parking lot. If it is CCV issue(and I've solved it with mod), how can I clean the sucked up oil gunk out of IM/ventilation lines? I already did the return hose to dipstick removal/plug(EVERYTHING was BONE DRY down there-no oil leaks, etc) and that drain hose had a few drops of oil inside it(nothing major). I tightly capped metal drain port on base of DS with a 3/8" cap from autozone, then slid return tube over that(cuz of oil in RT) with a little effort and it all worked good. I've owned X since Dec 2003, and do not remember having the CCV system replaced EVER since then!!! I did have engine pulled out by mechanic and a LOT of stuff replaced, but don't think I did that system(D'oh!). 1st pic is of air distribution port(all 6 look same), 2nd pic is small 5/16"(?) port on air distributer(showing a CHUNK of something) after I cleaned it with brake cleaner a couple times, 3rd pic is looking in to vent port on top of engine.
Any help or advice would be appreciated

Did you take your spark plugs out to check for oil on them?

Hello.i would to try this DIY but the PCV valve you added I can’t find on eBay or somewhere.
I can’t buy from autozone because I’m not leave in US
So someon else who could suggest me any other Eshop in Europe or any other PCV valve who will work in this DIY?

- Long-term Follow-up. My mod setup was in thread # 164, Dec. 2016.

- 15K miles later, zero oil consumption!

Before this mod, my oil consumption was 1 qt/300 miles! I was not happy!!!

Sincere thanks to the original poster...

10,000 miles and two years of driving in very cold weather and short trips. I never have to add any oil. There is not any mayonnaise type goop in the valve cover gasket!

I have a really bad idle in D and R (red lights). Smooth idle in park and neutral. Car seems to drive well. Usually use qt. of oil about 500-750 miles. I have done just about everything you can think of to this car except CCV. 2001 X5 3.0i and 187k miles. Do you think this could be my culprit? How are cars with modification? Are they all still ok? Are their any new updates?

Yes,

Do the CCV Mod and you WON'T regret.
