Thanks! Didn't want to sound like a DD...
BTW -- I think -- and I don't think real well... that you need a TOOL to pull the main caps off of an LS motor... Now maybe there's a "way" to wrestle 'em off there that you - or someone else - knows about.
But I would think that the rod caps might give you a good "heads up" and maybe even that isn't really needed if you think the bottom end is all good.
When I open my oil filters - it looks like someone filled 'em with brillo pad... Is that good?
