I recently replaced the upper timing belt cover gasket (left bank) on my 540i and since then it has a rattle on start up. It goes away after a minute or so. Car ran fine before the new gasket

The only mechanical part I had to remove was the vanos solenoid to be able to remove the timing cover but I thought I had replaced it correctly. Could that be my issue? When the cover was removed I checked the timing chain and it seemed good with no slack.

I haven't driven the car more than round the block so would this go away when the oil pressure returns fully to the solenoid?

Any other ideas on what it might be?
