A few spots of oil on the driveway doesn't necessarily constitute an "open wound", it's a minor inconvenience.
Old vehicles leak. If you can't fix a rear main seal yourself, it's a $500 - $1000 job at a mechanic plus whatever else they find.
I'd argue that a maxi-pad on an inspection cover on a truck barely worth that is a proper fix.
I know a few guys who fix everything as soon as they discover a problem, regardless of the cost or inconvenience. They also have spotless shops with everything residing in its designated space. I can't live or work like that, it just doesn't work for me.
I have neither the time nor inclination to address all the minor inconveniences, I'd rather play with the grandkids than head to the shop for a day or two to fix a leak that's producing nothing more than a couple of drops of oil on the driveway.
