Normal. Are you using 5W-30 or 5W-40 oil?

Still using. 0w 40 mobil 1

Here's the links for when the engine is warm http://youtu.be/oGHGCx77qIs

5W-30 or 5W-40 might be better than 0W-40 in this case and allow the oil pressure to build up quicker and reach the top of the engine sooner when cold.

The tapping isnt normal on cold, sounds like it could do with a good oil flush and change.
