Cavalier is 10 years old, so you figure some problems. Was running fine the day before, but the next morning was minus 8 degrees and it just wouldn't start. Heard a whirring noise coming from the starter, so replaced it along with the battery, which was the original. Starter turned engine at a snails pace, so I knew something else was wrong. Turned out to be the main timing chain tensioner. $1200 later, it's back to running like a top. At least I saved the money putting in the new starter, which was bad too at the same time.
Knocking or ticking started randomly one day, the sound changes with the Rpm's and i have had a head mechanic listen to the engine and says it sounded like something with the timing chain and timing chain tensioner, upon looking up such complications it seems i am not alone in this shitty situation. I am outraged that there has been no announcement or recall of any kind on these models with the 2.2 ecotecs.
