So after spending some time with other S54 nutters last Night I developed an itch to work on one
So herewith some pics.
The victim of my DIY. The current E46M3
Air filter box removed
Pollen filter tray removed to gain access to rear part of the intake manifold
And the intake manifold removed. Lovely watching those throttle bodies :drool:
And another pic pointing out the idle control valve. This is the extent of the diy I wanted to do today. Clean the throttles and icv.
Intake Mani out
Some pics of the dirty ITBs
The residue that you see in the last 2 is just some itb cleaner from liqui moly. It took a while and a lot of tlc and elbow grease but I managed to clean them up nicely.
The throttle acutator I pulled down and held it open using a vice grip. This gave me access to clean the rear end of the butterflies as well as the deeper recesses of the throttle body. I also took some snaps to show the rough surface deeper inside the throttles. I believe this is to promote swirling and mixing as its right in front of the injectors.
Mirror like finish
The ICV out and cleaned
Mani cleaned
