Sounds like the valves are not closing properly. Something in the valve train is damaged. Could be a bent or broken valve, broken valve spring, broken or bent rocker arm, bent push rod, etc. Low compression combined with back firing thru intake would indicate a damaged intake valve component and back firing thru the exhaust would indicate a damaged exhaust valve.
NO it is an interference motor 180,000 broke timing chain, bent #3 exhaust valve, luckily it must have stopped quickly as no more were bent.
your timing can not be right
Intake valve and exhaust valve.
yes a bent valve will not seat properly. can also wear the valve slide and ruin the head.will also cause backfiring and loss of power. sometimes a bent valve will breakthen fall down and punch a hole thru the piston or the side of the cylander bore so yes a bent valve can cause further damage to your engine
Gonna have to pull the head and find out what's wrong. Could be a bent valve.
