So whats your thought?

I was not in favor of opening the clearance up. That is really 'old school'. The clearance is worked on the rod's eye deformation, and is set to suit the oil used. The old way of opening them up, was due to the heaver viscosity of the oil that was used then. We now have oil that has all the property's, at a low viscosity, so the clearance that the Eg33 has, is set up for the low viscosity, that they recommend.
