Weird loud noise after n20 timing job
as title states I have a weird noise happening with my n20 the car is specifically a 2012 328i.
It has this consistent loud noise when the engine is on, noise is consistent with rpms and showed drivetrain malfunction upon first start up after timing job for VANOS but did relearn procedure and idled the car for a couple minutes and no more check engine light or drivetrain malfunction but noise is still present so i’m very stumped on what it could be. Engine doesn’t look to be moving or shaking violently when running.
Disclaimer: I have no clue how this car ran prior to this timing job as I purchased the car from a reputable shop in the bay area stating it only needed both chains and guides done but customer decided to leave the car after being quoted too high
