I'm looking at doing a piston ring soak, and most instructions I've found suggest alternatingly pouring B12 into the cylinders and turning the engine by hand to work the grime free and get the solvent into the cracks.
However it looks like the crank wheel is very tight in the engine bay and it's not clear to me how to get a wrench in there to turn it, or if I could even move it more than a few degrees. I think I've also read that the accessories on this engine resist hand turning? Is this the case?
Has anyone done a ring soak on this motor, and what was involved?
