Small block crankshaft endplay

At half an inch, it would have been making a lot of noise for a long long time. It was eating the rear cam boss the whole time, so you'll be looking at fixing that when the engine comes out. And Ima thinking the crank will be toast and maybe the bulkhead itself. When mine did that; I had just won a gate-prize of a 30gallon drum of ATF . After the oil was all gone,lol, I finally pulled the engine.
