so ive had the vehicross for about 2 weeks now and after fixing almost everything that was wrong with it i have it running well and riding smooth except for one really annoying rattle somewhere - it sounds metallic - almost tinny - and happens the most when the engine is cold or coming off of a stoplight - almost always when i start the engine - my first thought was a heat shield vibrating somewhere and i thought i would take them off and wrap some heat tape inbetween to soften any metal on metal vibrations but i could not find a single one that is the least bit loose - my next guess is maybe a bearing in one of the pulleys or maybe something to do with the clutch on the air compressor - however turning on or off the a/c seems to have no affect on the noise whatsoever - any ideas?
