I finally got around to replacing the timing chain tensioner on my 2007 Cobalt. I did this very same job on my 2005 about a year ago. The new tensioner fixes the start up rattle that both these cars were producing. It seems to be a known issue as GM redesigned the tensioner.
I wanted to share some pictures of the engine. It currently as around 140k on the clock. I have own it since it had 20k. Car is used pretty easy with mostly highway driving and few short trips. All but two of the oil changes have been synthetic oil. I use mostly what I get on sale and run the OLM down to 10-20% which equals to a bit 7.5 to 10k OCIs. What do you guys think?
