I am rebuilding a 2 liter engine out of a 82 Spider, neither of the Manuals I have (Pat Bradens Restoration Guide and an old Haynes manual) make reference to a thrust washer between the idler pulley and the timing cover. I appears that there was one on there before and I also see that Center Line has one for sell. ???????????????? Nearly the same question/problem about the Oil Slinger. Do all the two liters require an oil slinger (between the oil pump drive gear and the cover) ????????????????? Any advise is greatly appreciated........Thanks
