Have you verified you have pressure at the VVT solenoid?
If you think you have a wobbly sprocket (broken or incorrectly installed) you need to correct it. Why not take off your access cover and inspect it?Alternatively, it could be that the access cover and seal are OK, and the sprocket/cam is wobbly, which would cause the same issue
The sprocket's advanced timing is locked until advance oil pressure is applied, so it acts like a solid gear until positive oil pressure applied by the VVT solenoid. You can't turn it by hand, it's connected to the timing chain / rest of the engineCould the sprocket be locked up? Are you supposed to be able to turn it by hand?
If you removed the original flat disk and placed an O-ring on it you made the same mistake as me and need new disks found only on new access covers as far as I knowI have tried putting a standard o-ring on that nipple,
