Timing Chain? on 2002 Pontiac Sunfire

Engine stopped running. Turns over fine. No compression in 2 cylinders. Pulled valve cover and when turning engine over the valves do not operate. no visible valve problems (but have not seen inside cylinders). Is this likely a broken timing chain? Is the 2002 2.2L (gasoline not diesel) an interference engine?

Sounds like the timing chain failed and chain driven engines are usually interference engines so you probably have a couple of bent valves. The only way to find out is to do a compression test or pull the cylinder head

2.2l ohv engine is non interference engine --- timing chain tensioner fails 2.2l ecotec engine is an interference engine that will be damaged if the chain fails I think your engine is the ohv engine which means you need to replace the timing chain and tensioner align timing marks and engine will run fine
