1992 Oldsmobile Achieva 4 cyl Two Wheel Drive Automatic 170k miles

so my sister gives me this car. It has slight overheat problem. Dont let it idle too long! Gave to brother to drive and a miss developed. It got progressively worse until car would not start. Checked spark and plugs and all good. Did compression check and 1 cyl no compression another low. Started to tear down, took off cam and turned over engine. Now it has good compression on all 4! Checked timing chain was fine and timing marks lined up before removal. Is it the lifters? Can they cause no compression? Thanks

If a valve stuck open, it could cause that.
