Thanks for the reply, have been doing some searching and found a Ford TSB on these engines, apparently they have alot of noise issues. Possibly what they call the VCT phaser, somehow adjusts the valve timing to engine load.

heres a link to the bulletin if anyone else is having this problem.

Does have a crankcase full of 5-20 by the way.
