I opened up the replacement 383 for my 71 Satellite wagon and found bits of metal and plastic in the oil pan. The sump was full of the plastic bits but I couldn't find metal in it. So I pulled the timing cover to check the chain and sprockets, and there was a fair amount of the plastic missing, aswell as some of the sprockets teeth where the plastic was broken where very chewed up. The crank has no end play to speak of and the rods all seemed to be pretty solid. I ordered a replacement timing set which should be here this weekend. What was the purpose of the plastic on the timing sprocket?
