Can I check the timing without removing the pullies? It looks like I can get the upper timing covers off, I'm more concerned with bank 1 since that's where my crank code is referencing (p0341). Can I visually confirm timing and if so, what should I be looking for on bank 1? I have replaced my bank 1 oil control valve and cam position sensor so those are ruled out. Idle is a little rough and car is down on power. It's an 07 Santa fe with 2.7 motor.
