<div class="bbWrapper">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.</div>

<div class="bbWrapper">The tapping isnt normal on cold, sounds like it could do with a good oil flush and change.</div>
