N63 VANOS TIMING ISSUES w/ pictures
Hey guys so I'm getting 130308 which indicates that there is an issue with exhaust vanos in bank one.
I did swap, clean, replace with new solenoid fault stays at the same vanos. Ista stretch test passed. So I'm about to pull the trigger and open bank 1 and check the timing although in ISTA timing seems to be okay. So I'm thinking vanos gear bank 1 exhaust is probably bad. BUT Why if I perform one by one each vanos test using ISTA all 4 fails? Pulling valve covers on this engine with engine in the car is no joke so I would like to hear some tips or ideas before I do so. The fault code pointing with no doubt that something is not right with exhaust bank 1 but why the hell all vanos fail? Btw fresh oil. Drivetrain malfunction in seconds no matter the condition cold hot. Engine sounds okay no rattling noise no misfire. |
