21 stud motor oil leak rear of pan area

[Jack E/NJ]

As I recall on my 21-studder, there seemed to be a leaking deteriorated. broken & misaligned cork/rubber composite pan/slinger gasket. It's shown in red highlight on the VanPelt image below. A replacement wasn't found or included in my gasket set nor did I find a part number. So a replacement was fashioned from an old neoprene spin-on oil filter ring gasket held in place with contact cement. Jack E/NJ
