I read on here a while back about timing changing during a retorque but just passed it off as a joke. I retorqued my T/D today when cold to 100 from the 85 that was on it. It is a new head, milled block {.005}, 12 m/m studs with a fiber Victor Reinz gasket. The engine does have a little less power than before and even idles a little slower, smooth but slower. Could the timing actualy have changed? It sounds riduculous but that is exactly what it feels like, anyone ever heard of this?
