Time for valve stem seals... 2005, 4.4i, 113,000 miles

Hi guys, being a do it yourselfer, I think it is time for me to tackle the dreaded valve stem seal replacement job on my 4.4i.

Iím definitely open to suggestions but at 113k miles and smoking like a mosquito fogger after idling for even a few minutes (nice big plume of white smoke) I think itís time to bite the bullet.

I have replaced all of the CCV components, bumped my oil to 10w40 synthetic and still smoking after any kind of ďminorĒ idle time.

Strange thing is that it came on quick, like one day I didnít notice it and the next day POW, smoke, and it only seems to be getting worse.

No loss of power, no rough idle, no codes, nothing but smoke and sticky tail pipes.

Thoughts?

I *swear* on all that is holy replacing the seals made the thing faster. Even though I replaced mine proactively, it was a HUGE relief to be done with it. I mean, *maybe* it was because I knew I could hammer the gas without fear of first response. But maybe what everyone says about these things is true:

They don't really start to run right until about 115k anyway.

That is too funny!! I completely feel that way - crap... Iím ďthat guyĒ pulling away from the traffic light with the mosquito fogger... LoL...

In all seriousness, thanks Prop, I appreciate the encouraging words and hope to have this thing for many more miles to come 🤞🤞

most of the fear is in the un-knowing. It's a bit scary diving into a motor the first time fairly deep, but i've done timing chains on a couple M62 now and swapped a couple heads at the same time, did most of the job solo with step-by-step online. Take your time and when something goes wrong as inevitably happens, stop and take a step back, make a post with photos and somebody will be around to give a hand.

You're in luck

A couple of months ago I fixed this very issue on my 2005 4.4 with 140k miles, so every little detail is still fresh in my mind. Here's the thread that I added my experience to: https://xoutpost.com/bmw-sav-forums/...-seals-12.html Go through it - lots of info in there.

Please have no fear But I understand coz I had the same thing - fear of the unknown as already pointed out. YOU CAN DO IT! To put things in perspective, I'm just an avid DIY'er and a software engineer by training, who happens to just like wrenching in my garage on my back, as a way of relaxing after being all day in the digital world gymastics

If you decide to pull the trigger, let me know. I still have every single tool you'll ever need for this task, and you can borrow them - serious.

X5only, brother, I could hug you right now!í

Putting some lower control arms on my wifeís Buick now, but as soon as I have those knocked out I am going to burn your post into my memory about 10 times before I jump on pulling those valve covers and actually looking in to the belly of the beast.

With regard to the tools - THAT IS AWESOME!! I was slightly bummed to have to spring for the AGA Tool but being all but required to do this job... Let me get through your how to post and Iíll PM you aside to talk more about the tooling

Dare I say - I love you guys 🤣

Yea don’t stress. I have been soft preparing for this for a year now. I get the smoke after long idle. Like a car wash.

I say use the bungie chord in the spark plug hole instead of air pressure. Take your time, and make something so that you can lay over the engine. I plan on making something out of wood that will span fender to fender. Other than that, I have no first hand experience, yet. Lol.

Thatís too funny, to avoid that I kept blipping the throttle as I rolled through the car wash yesterday... I felt bad for the poor guy behind me if I let it load up and then mosquito fogged him as I dropped it in gear to pull out of the dryers...

I read about using a bungle cord as well, seems significantly ďsaferĒ than using air as long as you use the rubberized ones that wonít leave ďfuzziesĒ in the plug threads as you pull it out.

And I really like the idea of building myself a small shelf type unit to lay across the fenders! Good call, Iíll snap a pic of anything I might throw together and let you know how it works out.

Iím sourcing and ordering parts now so it will probably be a week or two before the actual tear down and dig in, will keep you posted

Yea keep us posted.

I have a seat cushion from an old chair.

Use soft pine, the shit they use for 2x4 walls, as the wood to sit in the fender lip. I would also pad the wood with some thing. Leather, wool, something to compensate for contour. Then 2, 2x4 on edge across the engine. Then screw seat to where I need it as I go between the on edge 2x4s. Hope that explains it. Figure make it lay somewhere in the front of engine bay as you will only really need it to work on the back.
