Matt and all, A quick word re: harmonic balancers: do not trust the "reference" mark on yours - unless you have tested / calibrated it against TDC . I recently took "a pile" of used harmonic balancers I had accumulated over the years, when disassembling engines; and I checked them on an engine that was at TDC, on a stand. Out of about 10 balancers, only two were accurate to within 5 degrees . The others were all "out to lunch" - some by ten degrees, some by twenty degrees, some by a whole lot more. If your harmonic balancer is original and has not been rebuilt, there is more than a good chance that it's no longer accurate, and that the outer ring has "walked" .
