"#3 cylinder's only
showing 130 psi vs ~160 for all the others, but we did a leakdown check that was OK"

Ken, is it possible that your leak down check passed because the hydraulic lifter on that intake valve is not pumped all the way up, like it is when the engine is cranking for a compression test, or running and puffing back through the intake?
