I did find a vacuum leak around the disa valve with the smoke. Fixed that and the trims came down a little bit. Ltft is now at 8.7 on both banks. It was at 12 before and may come down more with some driving. I'll have to wait and see.

I'm wondering if burning all of the oil contaminated the o2 sensors too. I'm still getting a tiny bit of oil burning smell/smoke at idle.

My 2002 X5 3.0 is using oil. It's hitting the ground tho so I'm guessing my CCV has already ruined my valve cover gasket.
Hopefully not my valve cover. Fingers crossed.

Sooooo anyway.....I am confused. I saw a pic (maybe here, maybe not) of this CCV delete done with a big loop near the pcv valve to keep it vertical.
Is that recommended?

Also does anyone know the size of the dipstick tube so I can get some of those push on nipples that are so tidy?

Lastly since this bypasses the CCV does that mean I can completely remove all the other CCV related items?
Items such as the valve itself, the cut off hoses, connectors, the now unused dipstick hose, etc.

Thanks for this awesome write up.

I can say that the selection of plugs I got at AutoZone does not have one big enough for the dip stick tube.

Yes, you can get rid of all parts of the ccv. It won't be connected to anything anymore.

NONE OF THE NIPPLES I GOT WERE BIG ENOUGH EITHER, i USED A PIECE OF HOSE AND A BOLT, CLAMPED THEM DOWN TIGHT.

I re used the hose off the dip stick tube put a bolt in it with clamp tie wrapped the hose to the dipstick tube .its way down there and you cant see it that easily anyways.

You can see the dip stick tube if you lay on your back behind the drivers wheel and look up past the front drive shaft. Mine did not have a hose clamp on it and I was able to reach up and push it off with a screw driver. I'm pretty sure it was 5/8 " fuel hose I used and plugged it and clamped just a short section then reached up and slid it on. You could also reach up and cut off the existing hose and use part of that. I just finished this mod and used the method in this thread that includes the "t" so that both ends of the intake manifold are hooked up. I thought this was good backup since the hose to back of the manifold is a small diameter and could narrow over time. I just left the dip stick hose dangling and did not remove any of the under manifold CCV apparatus. It really was very clean and simple. Read the whole thread and you will be very confident tackling this!

OK Thanks I'll try to find the dipstick tube and hose later.
I have not done this CCV delete yet...just weighing my options.
Didnt see it earlier but I didn't have ramps so I wasn't crawling around much under there.
Would it be ok to just leave that hose hooked up or would the vaccum cause problems?
I am really more worried about the loosing oil situation. I did look for the CCV but can't see it at all.
Not sure if I'm looking in the correct place.
I had the intake manifold ducting, air box , intake boot, DISA, ICV, drivers side engine cover and the under car splash guard off this morning.
Was replacing the old intake boot. And no I didn't take all that stuff off to replace the boot.
Was thinking of doing this delete to be done with this damn CCV disaster.

If I understand it correctly...and do this delete then later want to change it back all I need is two new hoses to replace the ones that got cut up.

And of course >>>a new CCV unit<<<.

You can't see the ccv at all. I would totally take the intake manifold off if I did it again. I've done the whole job twice now and can do it with the manifold off in under 3 hours now. It sounds like it takes 3 hours of bad words of you leave it in anyway so Id take it off.

:dunno: I am doing good to change out the intake boot, change plugs or do an oil change.

I had to have DIY's for those. Anything rather simple is ok. LoL

I don't know if you'll want to try to tackle taking it all out then. Just putting the pcv is easy enough though!
