Until your vehicle leaves puddles until your needing to add oil bi weekly. There is nothing to worry about. Drive it. You can find oil stains and gunk under any motor.
I took an older car in for a tire alignment was told the lower control arms with pressed in ball joints were shot and tie rods were shot, wanted 1400 dollars to repair.
I bought the parts on line and did the work myself. The old parts looked fine. I took them to a reputable front end repair shop...
I had a 79 spitfire that tipped over alot, and a 84 sprintfire nice sled, 340 liquid cooled oil injected direct drive. I put dual carbs and ported it and shaved the heads it was snappy but the direct drive limited top end to 65 or so.
I just put up a 28 by 40, 2 overheads 10 foot walls metal roof smat siding insulated and drywalled Did the work myself except ste prep and concrete and I have 30,000 in it. Osb was 22 a sheet whenI did it
