I have a 93" S & S cone shovelhead with dual plugged stock heads in a Paughco wishbone rigid frame and a ratchet top 4 speed. I built the bike in 1992. I recently replaced the oil pump with a TP oil pump. I updated the breather gear based on what SS tech advised me on their new gear and replaced the lifter block, cam cover gaskets. I first had a oil leak at where I thought was the rear block at gasket surface, then after cleaning up started it at idle and saw oil leak at the rear intake push rod tube. Wanted to know if anybody had advise on what the hells going on. Also want to know on shovelhead the hole in lifter block that aligns with hole in case, is this a pressure oil supply passage to lifters or a return oil drain hole. Does oil from outside oiler line to rockers drain down in pushrod cover. My manual only has oil diagram for Evos. Thanks for HELP!!
