My '53 GMC has been running well for a year or two, but recently when I drive it, I hear some awful sounds coming from the engine or tranny. It starts after I've driven it for a while and the engine has warmed up. It sounds like metal on metal so I am wondering about fluids. The oil is full, don't know about the tranny fluid. Also wondering if the sound is coming from the water pump, fan. or some other moving part that might need lubricating. Any ideas?
Thanks,
