@@actionmade I’ll be testing them too see witch ones are leaking, assuming it’s cyl #1. I did an oil sample and it indicated excessive fuel dilution, 3%
@@Kamshaft the only time i have seen super knock codes are on cars with stuck injectors or ones that have been tuned improperly “super knock” is a frequency that the sensor picks up
@@actionmade this n55 with di has an eccentric cam on the intake side, however the cam phasers are both oil pressure controlled hence having 2 vanos solenoids when the phaser fails internally you have timing codes particularly camshaft installation faulty
@@actionmade I measured the all the bearings to make sure they were the exact same as the old ones (to the thousandth of an inch) I probably should have plasti gauged them, expensive mistake.
UPDATE! Root cause of bearing failure was due to a leaking injector.
@@actionmade yes it was!

Bmw tech here you likely have a vanos gear failure or eccentric shaft failure
Failure is actually in the bottom end, what do you know about super knock codes?

Your a bmw tech and yet you have no idea that vanes only exist in n52/n51 platform LOL
