I have low pressure after prime/startup 10 and lower builds up as engine warms and after warm on freeway gets up to just past 40 but dos'nt stay seems to fluxuate with rpms good pressure no louder lifter noise. I do service work (garage doors) so when I go to leave service call I have lifter noise and trucks acts like this throughout the day any help GO!

GET it fixed SOON the knock is telling you ain't got nuff oil going were needed. You have a bad "O" ring seal on the pick up tube to oil pump. best way to fix is remove oil pan and remove the pickup tube (one bolt) then get new "O" ring.
If the old "O" ring looks good you will have to replace the oil pump which entails removing the water pump, Harmonic balance pulley, timing case cover. the the oil pump.
I replaced my pump which came with new "O" ring. Gaskets were separate cost? With pan off a good time to inspect other moving parts the have been moving with out oil flow also.

Check your coolant, if it has dropped that means you have a cracked head and its thinning your oil, i had a 04 with it.
