loud noise when clutch engaged and idleing noise help!

[HankHill]

Ok so my truck makes a noise when I engage my clutch but ONLY when the truck is already moving when it is at a stop and I use the clutch it is fine but when I'm rolling to the stop light and I hit my clutch it makes a loud clunk it sounds like it is coming from the front you can feel it too, today I started my truck to let it warm, it is about 40 degrees and has rained past two days constantly,so I come back and here this tink noise coming from the engine I've never heard something like it sounds like taking a empty soda can and tapping it with silverware lol and it will make this "tink" noise every few seconds I cannot hear it from inside the cab its just a single "tink" every few seconds I popped the hood in the pooring rain to do a brief check and the big pipe left to the coolant res has soot on it any ideas on where to start with this please help

you have an exhaust leak at that pipe i cant think off the top of my head what pipe that is though try tightning the clamp and see if your noises go away
