hi all,

i was wondering what a healthy diesel engine sounds like. mine acts healthy but 
sounds as if there's an extra high pitched tap-it noise akin to the valves on 
an old small block 350 in need of adjustment. not knowing much about diesels, i 
thought i'd query the community at large. is there a way to upload a sound 
recording to the group's page? thanks -rob
