Pontiac g5 cant remember the year off hand. Sounds like the timing chain has slacked out. I have a full engine and trans out of a cobalt with 70k . Also a ton of other cobalt parts.... If u want it all make me an offer. Id like it all gone. Lots of good parts to be had. Lists and more.pics. Upon request. Great if you want to do some rebuilds too. 2.2l ecotec
