hey welcome to the site. today @ school i was working on an S10 with a pushrod 4 banger. it had the same compression story. it turned out that it had a bent rod which turned the rocker arm so it was pushing on the spring insted of the vlave stem. in turn the spring broke loose from the valve and the valve dropped just enough to release all compression but not bend the valve. If this happened to you it could have possablly wore out the valve guide from not getting pushed strait in.

Long shot in the dark? yes.
Good luck

it could be your piston rings or valve guides. might also be that the cylinder is ovaled or has some deep scratches in it.
