let your X5 really warm up

[J.Belknap]

I get going once I'm done setting up my music. However long that takes.

Glad there are still people like JCL here to clear up misinformation.

When I got the X I did notice the mustard color oil at the oil cap and from my past experience of owning an air-cooled PORSCHE I knew what it was. Stop using the X for short drives and more frequent oil changes (Not the 15,000 miles recommended by BMW) has resulted in no more mustard colored oil.

Right on brother....................

It was a balmy 12 F degrees here this morning and even after sleeping in the garage, my X would not stay running on its own until completely warmed up. Was like that last Winter too, but was outside all last Winter. And yes, I have gone through all the threads about rough idle and engine dying out, etc. Got CE light yesterday, checked with Peake R5 tool, and got about 20 codes...mostly Cylinder Misfire for all 8 cylinders. This morning, no CE and no CODES. Went home for lunch, CE, same codes. Runs like a top once it's warmed up...just does NOT like cold weather at all.

Have you done any troubleshooting based on what you found in other threads?

I had similar behvior with my 2001 4.4i. Turned out to be split / mushy oil separator hoses. Wouldn't hurt to inspect them as they're easy to check. Remove the BMW cover and look behind the engine on the passenger side. If you want to know more search on my name and "oil separator hoses".

I checked for air leaks in the intake elbows and last week had a smoke test done with nothing popping up. I will inspect those oil lines tonight and might just go ahead and order the oil separator and all related lines from Pelican...less than $100 for all.

I do have a question...I keep seeing posts about replacing the CCV but I can't seem to find any related to my 2001 4.4. Does it even have those?

It's the backing plate at the rear of the intake manifold. Part #11-61-7-508-541. $79 from Pelican. When you get it, open the package and inspect it. there is a tiny hose fitting (standard vacuum hose size) that I discovered broken on mine when I went to install the new one. Luckily Pelican was super awesome and sent me a warranty replacement next day air!!

I did the oil separator, all the hoses, and the backing plate without removing the intake manifold. There's enough room to work, but its awkward. It would be easier with the manifold off. And if you take the manifold off, I'd go ahead and replace the valley pan gasket, and depending on mileage, maybe the waterpump...good excuse to replace as much stuff as possible while you're there.

Well I just received my valve cover gasket kit in the mail and was gonna do them next weekend because of the oil leaks, but I can wait and do all that other stuff at the same time since I will have the manifold off for the VCG's. I have learned that if I keep the engine under 3K RPM all the time, I don't notice the burning oil smell when I get out of the car. This may be old news for some of you but my guess is that over 3,000 rpm the valves and lifters are really sloshing the oil around and forcing it out of any possible leak in the gaskets, thus dripping on the exhaust manifold, thus causing the bittersweet smell of burnt oil (antique Porsche owners will know what I'm talking about).

The oil separator is the CCV system.
