Bank 1 Camshaft Vanos and Timing Issues
 

greetings

I have a 2002 4.6is 90k miles and also has dinan CAI and throttle body.
back in Dec the X lost all oil pressure and essential stalled out, resulted in getting crankcase vent valve, cyclone sep. upper timing chains, both valve cover gaskets all replaced on passenger side Bank 1

Pick the X up SES was still on, was told by indy german specialist reason light is on, vanos, valve and gaskets need to be replaced on driver's side Bank 2

I drove the vechile for roughly 500 miles and have experienced stalling, skipping, jumps in idling, and skips at low RPMs, codes are P0174, P0021 and P0171. Codes are indicating Bank 1, I believe ????

Does that mean my timing and Cam still needs adjusting from the indy shops on Bank 1 ?
Therefore, there is no need to conduct repairs on Bank 2 ?

I need some guidance on going back to the indy shop and getting my continued issue resolved on Bank1 and not begin replacing parts on Bank2


thanks for you anticipated input

Ron
