4.4 Inject SeaFoam

[SLX5]

I have the white smoke in my 4.4 X5. Replaced the CCV valves already, yet the condition persists.

I want to inject SeaFoam into the engine. Heard the best way to do is through the vacuum line. Any suggestions on how I should introduce to clean up all the gunk in the CCV system?

Wow! sounds like just about everyone is having the smoke issue, including myself! Think its about time BMW has a recall on this issue.

Yeah no Sh**. Last BMW I will buy used!

It is the ultimate driving machine if you get this brand new and dump it around 60K. Love the machine NOT the maintenance.

If I buy an X it will be brand new and dump at 50 to 60K. This this the second I have owned. Not fun.....

Yep used BMW's have way too many issues.
I owned e36,e46,e39 and now the e53 and they
have so many issues, but I still keep coming back for more lol
I'm with you though next one is gonna be new.
I did the Seafoam treatment to my engine last month.
I used one bottle in the engine right before my oil change
The other I used in the Vacuum. Pretty simple you just take a vacuum
hose and stick it in the bottle and let it suck in some Seafoam
while idle. Once it takes it all in shut the engine down for a few
seconds then turn it on again. You will see heavy smoke for the first
5 mins. After that just drive around for a few minutes preferably
at night. The next day you will still get some smoke, but after it's all
done you will feel a difference and maybe your white smoke will go away.
