Did you change the gasket too? And did you put any sealant on it?

can you see marks on the underside of the cam cover where its been hitting? A rattling flywheel is often mistaken for chain noise, particularly when it gets warm

Done a bit more research into this as its baffling me! What's your engine code and the part number for the tensioner you fitted? There's 2 different tensioners for non-vvt and vvt engines. Also found out this could be a symptom of a worn oil pump or blocked pick up pipe.
