Some more maintenance. I think I mentioned it earlier, but while doing headers/CPV, I notice the Exhaust cam sensor was leaking. I decided to just replace both sensors (intake/exh).
Here's the leak (only exh side)
New OES(upplier) part from FCPeuro. Newer one is now gray and larger. Make sure to buy the o-ring! The intake comes with new o-ring, but not exh!
You can see the BMW logo ground off, it's a genuine part for half cost. Another pic of new sensors:
Exhaust is easy to change, just need a 5mm hex bit/key. Intake, however, is a PITA. Not only do you have to remove the manifold, but technically, you're supposed to remove the air and even fuel rail as the plug and wire for the sensor is hiding behind. I took a short cut that I'll explain.
There's a little plastic "cage" that you have to get out of the way
Now, you can get your 5mm hex bit back there, a wobble helps.
Since it's easy to do (2 x 10mm bolts), I removed the air rail for more access
Here, you can see the sensor's harness snug as a bug behind the fuel rail. So instead of removing the fuel rail and dealing with all those bitch clips, I just cut the harness so I could pull it out. Then, after installing new intake sensor, I plugged the harness in, and just stuffed the extra wire behind the fuel rail.
Also, even though I did a quick cleanout of the ICV, since the airbox was off, I wanted to do a better job. I got some new hose clamps as the oetikers are one-time-use, and I pulled the hoses of and cleaned everything thoroughly.
