Hi guys so I recently fitted brand new GM cam phaser pullies both intake and exhaust and also fitted 2 new solenoids but I am still getting the rattle on startup which goes away in like 3 seconds. You can still here the intake pulley very faintly rattling once it's warmed up.

Does anyone know if this is normal because am really not sure what to do now as I have replaced every component from the vvt system and I am 100 percent sure its still coming from the intake pulley because if you pull the plug to the intake solenoid when the engine is running it gets louder so its decently coming from the intake pully.

I have also recently changed oil and filter and I am using dexous 2 0w40 engine oil.
