Starting a new thread as I am now tuning and refining the shakedown of my running A4.
The first issue during several 5 minute runs on the hard is that I have noticed an intermittent wisp of exhaust or other smoke which has been elusive to locate. It may be the flange(which was replaced by PO with MMI flange in 2006). It may be at the exhaust pipe joint at the manifold or stack. Elsewhere. Engine compression (100 to 105 cold), temperature (90 to 150 5 minutes infrared multiple locations), oil pressure (40psi), and oil level all good. Exhaust pipe from manifold temp is 300 +-.
Here is the best video I have. I have watched it at .25 speed and 2x speed nothing determinative yet.
I will video during run tomorrow from stern of engine with best view possible of piping joint and then flange.
Welcome any diagnostic advice.
Note that I have not dialed in the idle yet, I would appreciate your ears; any thoughts on how the engine sounds as is?
Thank you. Stay well. Tim
