Time for me too add a picture, this is a rust spot i found in my drivers side door before i swapped them over, this was behind the electric mirror, looks like the water has been holding in the foam and has caused it to rust out,

Posted by Xcabbi, Does it slap or rattle? Rattle is more to do with timing chains and tensioners. Slap is more to do with lifters, rings, bearings or GENIII boat anchors
