Hello everyone! I recently notice a significant, what looks to be oil underneath the right side of my 7.3l engine block. It appeared to be the fuel lines at first, tainted with old oil from under my truck, but after I cleaned it up some, it may be coming from somewhere else. One of my go-to buddy’s said it may be the oil cooler.

Any advise or suggestions would be greatly appreciated!

 

Yep. Looking at the pics on my computer this morning, that is definitely the oil cooler. Riffraff has a kit that replaces all the gaskets and o-rings...
