Try running the engine and putting some dry lube or belt dressing on your belts and see if it goes away. I had a similar thing and that was it, just put some new belts on and all good after that
get half a broom handle or piece of dowel and press it against things with your ear against it on the other end, you can hear the vibrations through the wood. once you find out exactly what is causing the noise you can then look at fixing it
but as it sounds like its happening both sides i do agree it could be noisy injectors.
Yeah I'm thinking it sounds like injectors because when I turn it off it rattles in the injector/fuel line pipes is there anything that can be done to stop them being noisy still haven't upgraded the fuel pump yet thanks for replys guys
I ran some injector cleaner through it seems to have made no difference I'm gunna take it to the mechanic Friday and see what they reckon, the whole engine is noisy so it's rather annoying
