Hi all,
I recently made a number of changes to my 2007 E92 330d (M57N2), including blanking the swirl flaps when I had the manifold off for a clean. After some reading, I've now decided to reinstall them in the hope that it will help my primary problem - very stinky (but now smoke-free) exhaust when idling.
Below is a photo of the swirl flaps removed from my manifold (I'll give them a good clean before re-installing). Can someone please verify that they are the newer kind, not prone to breaking off and being ingested? The blanks I purchased were 33mm in diameter.
Secondly, I didn't have a torque wrench when I reinstalled the manifold so I just went by feel, but I would like to torque it up properly this time. Does anyone know the correct torque for the 7(?) large nuts and 12 smaller bolts?
As always, big thanks in advance for any help! :thumsup:
