Hello I'm new to the site and have a few questions. I have an 05 cavalier with a 2.2 auto. The timing chain jumped time and bent a bunch of valves. There are a few marks on the pistons but don't seem bad enough to cause problems. Should I buy a remaned head and new timing set and put back together or replace the complete engine. It only has 106,000 miles on it. And what all should be bought and replaced with the timing set because even if I put in a used good engine I will also replace that on it too? Thanks for your help
