Sweden Keneth, I don't know how sure you are of the source of the knocking - it's quite common for the hydraulic tappets to clatter for the first 30 seconds or so, oil drains out of them whilst standing for a length of time, and it takes 30 seconds or so for the oil pressure to get back up.. - Mark.
