would suggest that the first thing to do is short out the plug wires one

Mike and all--
I tried that one at a time and there was no difference at all--the noise is
the same regardless, just changed by the rpm's decreasing when I detached the
plug lead, but not lessened by a particular cylinder's not firing.
The noise is easiest to hear at idle,and has a hollow sound which decreases
as the engine is revved. It almost seems to go away as the rpm's increase. I
do not have a stethescope and it is difficult for me to pinpoint its location,
but it seems loudest when I am crouching in front of the grille--what does a
timing chain sound like when it is loose and/or failing?
Best--Michael
