You can also remove spark plugs to see if any or carboned up or other combustion problem signs.
Do you hear a popping or puffing sign at the exhaust pipe ?
Sounds like either a collapsed lifter or a rocker arm problem.
I would remove the valve cover and see if there any damaged rocker arms.

no i dont hear anything out of the ordinary from the exhaust. I'm getting worried its piston slap maybe i broke a piston skirt. i'll do some investigating in the coming week hope to not find anything too bad

of course i'm gonna rule out any valve train issues before i drop the pan and look at the bottom end
