Hello y’all I am new to this forum and I have been looking all around online for some answers. I just picked up this 7.3 with 147,000 miles. I’ve been driving it for the past 5 days and noticed a small pool of dark/oil like leak. I’ve degreased the valley, undercarriage, etc and it still shows up. It’s really hard to pinpoint the area since it’s leaking all the way down from the valley down to the pan. I haven’t lost any oil and i just wanted to see what y’all think.
