I thoroughly greased my shaped/conical washers (one thick one thin from memory) before fitting. I made the point earlier in this thread that they need to fit directly under the oiler bolt to allow them to settle into their natural and correct position by the action of the bolts shoulder bearing on them as it's tightened. I suspect when this doesn't happen you can expect Cain's experience.
Again from memory, the two washers are flat on one side and taper in thickness on the other. The two tapered surfaces are placed against each other and settle into a combined position to take up the tiny angular difference between the upper surface of the upper suspension support (plus bracketry in between) and the oiler bolt shoulder when screwed into the matching kingpin thread.
