2006 Malibu 2.2 litre, 207,000 miles. The valve cover looks a little better than the pics show and the valve train/head looks a little dirtier than the pics would lead you to believe. Engine runs fine, consumes 1 qt/4,500 miles. Timing chain has slight slop in the middle of the sprocket if I give it a good pull. Don't know if this is normal.
OCI has been anywhere from 5,000 miles to 15,000 miles. Average of around 8,800 mile per OCI. %60 city/%40 highway driving. Most winter days it sees one or two short trips of 2 miles or so but usually a small highway drive in the morning as well.
Oil has been mostly store brand conventional. Maybe 3 OCI's have been group III synthetic usually store brand. Remaining OCI's have been a mix of what I have, conventional and group III syn. The 15,000 mile OCI was all Group III.
I'm a little surprised at how dirty the valve cover is but I don't think I'll change anything.
Removed the valve cover due to a leak.
