DIY Solution to M54-M52TU CCV problems

[Rush]

Yep, I'm working on that as I have time.

The search function does not accept "CCV" because it is "too common".

To be fair, I have found a few things, but I am well aware that anything that include the word "Dinan" has passed into the "nearly impossible for me" category.

Oh, and I should say I'm finding cold country valves, just not for the M62.

Rats!

I just did this mod on my wife's x5 and now have a lean engine code. It smokes slightly at idle and my wife said the engine hissed for about a minute straight when she turned it off today. Does anyone else have high fuel trims with this set up? In using the same part # for the valve as the op.

Sounds like you have a vac leak somewhere, mine does the "hiss" for maybe 1 second after I shut the engine off. Fuel trims are stable, and have not had any vehicle produce smoke after this mod, any chance you installed the PCV the other way around ?

I'll see if I can smoke test it tonight. I don't think I have it backwards since the fat side goes to the larger vc hose.

I did mine and couldn't be happier! No lights and better yet, no sludge!!! if you got a cel after doing it, there's another issue, i triple checked that all my clamps were as tight as possible, because i'd forget one, i just know i would, also see if all the o rings in the air distribution block or tubes, whatever they're called are there and not pinched..

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.
