Intake side.

Dealer is doing my valve stem seals under warranty. They want some tool to do it without taking the heads off because, they say, the heads will probably warp and will need to get new ones. Sounds legit? I've been waiting 8 weeks now.

It can happen, but not sure how probable it is on the N62... Doing it insitu saves alot of dealer money. You won't have a ton of say in the matter when its a warranty job.

Anyone measuring their oil consumption rate? I'm making some mean smokescreens with my X during extended idling times. My engine has 112,000 km on it, absolutely ridiculous.

I'm running it harder from time to time when its all warmed up on on/off ramps to burn off any buildup on the exhaust side but not really banking on that for anything.

Anyone had issues with this clogging up the cats?

Any success with changing oil viscosities?

There's no miracle fix, oil vis change etc. You have 2 options:

1. Enjoy life, let an indy do it for you ($$$$$$$$)
2. Elbow grease, keep the $$$$$ in your pocket. And do this

ok.. so why does she smoking stop during the cold weather? I don't seem to be smoking at all anymore at idle at a stop light.
The only change is that I topped off the last 2 times with a heavier oil(10w30 i think)

You adding a heavier oil is a temporary fix your doing more harm than good in the long run your making matters worst.

agreed.. the valve stem seals fund has already started :)

Lol a word of advice when doing make sure they take the heads of or you'll be going down that road again. Did my wife truck A year now truck runs like a charm.

Lucas Oil Will Fix Your Smoking X
 

I know this is an old post, but...
I'm finally a member on this site and this is my first post. I bought my X5 with 164,000 miles and the dealer tricked me into buying this smoking monster. The short story is while I was loading my stuff from my old car into the X, the dealer snuck over and turned the X off. I was getting stuff out of my Mark VIII and I turned around towards the X and he was walking away from it. I scratched my head and wondered why he turned it off and just supposed for safety reasons. Whatever. He knew damn well the car smoked while idling too long and I didn't discover it for a few days. And I mean SMOKED!!! BAD. I read all about the valve seals and the EGR diaphram stuff(mine has the factory upgrade on it) and was just horrified.

I went to Walmart, got two quarts of Lucas Oil Stop. 500 Miles later, NOT EVEN A PUFF of smoke, EVER...

For what its worth for anyone reading this thread. I put in two quarts of Oil Leak Stop at every oil change
Lucas Stop Leak - Walmart.com

I also put 1 quart of oil stabilizer.
Lucas Oil Heavy Duty Oil Stabilizer, 1 gal. - Walmart.com

I also use SuperTech full synthetic oil. It runs perfect now, and quiet, and NO smoke. No time for the ensuing arguments about oil choice. I've always used this oil that Quaker State makes...

This will save you 5000-7000 dollars.

I'm not a mechanic. Try this at your own risk, it worked well for me.

Now going back to my ignition switch issue
my driver mirror issue
my two driver side door carrier issues
crummy subwoofer issues
coolant leak
windshield wiper tank leak
and rear camber issues

But it don't smoke anymore at 186,000+ miles!!

what a sneaky dealer!!!
thanks a lot for your input. I will definitely research this and add it to my list of possible things to do.
