Customer came in yesterday complaining of an engine knock on a 2010 Equinox with the 2.4L. We checked the oil and found the level just barely on the dipstick. Changed the oil and filter and the noise went away. This is the filter we pulled out. It's a Napa Pro Select that we normally use, but it had over 8000 miles on it. We've already done timing chains on this motor and these 2.4L's seem to be doing this more and more.
