Shit this is getting hard to explain. The only other way I can articulate it like when you hit your anti lock brakes and you hear the computer take over pumpming the breaks really fast but with bog and fat sound that pitches high then low extremley fast and very eratic.
That sound is unfortunately familiar...If it is what I think it is you pop open the back plate and look the crank pin and rod..the crank pin may be worn out. As I have asked before does it seem to have a lot of slop at TDC. By looking at the rod / pin you may see a gap showing wear. I hope this is not the case but from your description.....
Also does it seem to vibrate like crazy?
Hope this helps!
