Last owner apparently not a big fan of changing the oil

I had an old girlfriend that had a Malibu. Like 1979 or 80... Anyhow I did her family a favor once & changed the oil in the little 267 V8 that it had (2bbl). The valve cover gaskets were leaking onto the exhaust manifold so I bought some FelPro's and went to replace those too... As I removed the valve cover I see a hardened shell of oil & gunk formed to the shape of the inside of the valve cover that REMAINED IN PLACE when I took the cover off. It looked like it still had valve covers on it. No joke. THAT was the worst I had ever seen.

That engine lasted about six more months. I swapped in a junk yard 350 (kept the 2bbl on there) as a favor later too. Girlfriend had a fast tire spinning Malibu after that. :)
