I've done a few timing chains on the Oldsmobile 307 motor where the nylon teeth on the gears were stripped down causing a no start. Never saw one bend the valves.

Just a follow up to my review. I actually had my go to mechanic replace the timing chain and gears as a peace of mind repair. Also did valve cover gaskets and another water pump while it had to be removed doing the chain.

Just did a trip from Daytona to Key West, 900 mile round trip. Such a pleasure taking this car on that venture and it performed great.
