I performed a cam swap and have some smoking at idle. I replaced the valve stem seals with dual valve springs. I am curious if I am seeing a burning oil issue or too much fuel issue. The smoke looks to be on the light blue side, which typically means oil. It takes about 10 minutes before I see smoke at idle. I just started working the tune, good start up and idle.
During driving seems to go away, but when I accelerated the car back fires and sounds like it's running pig rich. The STFT at idle look good. I've attached the file and links to a couple of vids, one of smoking in cylinder number 1 and one showing the smoke externally. This all appears to be happening on bank 1.
The heat readings on the left bank are cooler by average 75 degrees using a digital thermometer. I pulled bank one plugs and they are black with number being the worse. I swapped them and same scenario after driving a few miles.
