engine noise worse when cold

[jessenewton]

hi i am new to this forum
when i start my car in mornings it has a loud rattle and is loud when reved,it gets quieter when bout half temp but still noisy,has had new head and timing chain so cant be chain hopefully,sounds like it on top of engine about half way,its under rocker cover or under turbo pipe that goes over engine
still runs fine but does seem a little sluggish and underpowered
could it be an injector

I left a answer in the other thread you posted in. It will be old fan belts mate. Start it up in the afternoon when the noise is not there and spray the belts with the garden hose. If the noise comes back, change all your fan belts.
