if after putting oil in your spark plug hole..and you cranked it over..and you didn't get any compression..then either your valves are bad..or your rings are bad..one or both...only way to check this for sure..is to tear the head off...take your rings off the piston..slide them down into the cylinder..look at the end gap on the rings..if they are out of spec..then they are bad...as for the valves..after you get the head off..with the valves still in...turn the head upside down..pour alittle gas into the head..if the gas leaks out..your valves aren't seating..or they are bent..one..or both..this is how you check your valves and rings

Agree^^^^ when was the last time it was running? and how was it running? you possibly could have bent a valve
