I developed a noise in my engine that upon partial disassembly turned out to be two of the three bolts that bolt the timing gear to the cam had backed out and were hitting the timing cover. Apparently, I forgot to locktite them or install a cam lock plate :clonk: the cam dowel is now missing ( probably in the oil pan and won't come out ) and I need to replace it. can you purchase a new cam dowel? can you just remove one from another cam? are SBC and BBC cam dowels the same size? any answers or comments much appreciated.
