If the noise is coming through the exhaust it sounds like you either have the timing belt off a tooth, or didn't get the chains spaced correctly when installing the lifters. With the engine set up on TDC, timing mark on the crank pulley has an alignment mark, exhaust cam has an alignment mark. With the valve cover removed, there will be two marks to align the camshaft chain gears- there should be 16 rollers between the teeth that align with these marks. Note that the teeth will not EXACTLY align with the marks (for no good reason, VW logic!) but will be slightly OUTSIDE these marks

If you are checking for low oil pressure (common on the 1.8T) then look into the oil pickup tube for any signs of carbon "grit" clogging the pickup
