Too much background noise in there to say. Does it get worse when you're accelerating? Not revving it, but driving?
Something you can do to try and narrow it down is going back to basic mech-a-neckin. Get a long screwdriver or socket extension, and carefully, while engine is running place the end of it on thse things you can easily reach (alt, PS pump, bell housing, etc.) and the other end to your ear. those nifty mechanics stethascopes are evn better, but most folks down have those layin about.
Basicly you'll be able to hear it louder & possibly chase it to the source. At the very least you'll know what area of the engine it's coming from.
If it is rod knock you may not hear any real difference unless you listen to the lower sides of the case by the oil pan where you'll get better sound transfer.

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion! :P
