ok, valve cover off. plugs removed, fuel pump fuse pulled. turned engine over for about 15 seconds. oil aplenty....nothing loose or broken. oil coming out of lash adjusters just fine, timing chain picking up oil, no problems. had my friend turn over engine while I put a long, skinny screw driver on each and every rocker arm. zero slop. I'm going to try some Marvel Mystery Oil, and see if it helps. when the engine is turning over, it is not making a sound. however, as soon as it is running it sounds like it has a collapsed lifter.
