2002 Pontiac Sunfire Q&A

2002 Pontiac Sunfire Question: Timing Chain?

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? -
Answer 1
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 -
Answer 2
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 -
