| Valve retaining tool holding an intake valve in position (inside view) | Valve parts: Piece of packing string, inner and outer springs, inner spring support washer (and packing chamber cover), compressed teflon packing (after 5000 miles use), valve retaining clip (obsolete; no longer used), outer spring support washer, neoprene valve seal (NAPA # CEP 216-1021) | Teflon packing wound on valve stem ready to be hammered down. |

| Packing chamber cover in place before hammering | Packing chamber after packing being compressed by hammering. Note the base of the packing cover is very slightly proud of the edge of the outer spring washer, indicating about .020 of height added by the packing, a critical point. Too little and the packing won't seal. Too much and the inner spring will be over compressed, possibly becoming coil bound, which would cause parts to break. |
The neoprene seal in place. This
seal provides additional oil control, which is helpful when the intake
guide is worn. Disclaimer: The long-term effectiveness of
the neoprene seal is unproven, and the neoprene seal should only be
considered a temporary repair of use until an overhaul including valve
guide replacement is conducted.
