What you are describing might be some bearing noise just before the oil pressure comes up, it is called dry start there are a number of ways to cure it, first check and make sure you have the correct oil filter on it, one with an anti-drain back valve in it, then you could try a friction modifier in the oil, one that is designed for dry start problems, you could install an electric pre-oiler that will pump oil up to pressure at the flip of a switch before you even crank the engine, or you can have the engine's rods and main bearings checked and replaced if needed, possibly even do a crank kit, and remember if you do any engine work replace the oil pump.

Thank you (tennishoes) I am hoping its the oil filter as this is the second motor I have put in this vehicle in the last 12-18months

If you're having startup noise tapping, then you have a loose engine. Heavier oil and Duralube or Prolong, etc is MANDATORY... I'd run some high detergent oil, like tranny fluid in it for a 150 miles before you change the oil.
