Help, I have heard two different stories from two different people......so can anyone tell me which is true.
Replacing valve seals on a Chev small block, where does the small o-ring go on the valve stem. Does it go into the grove on the stem and if it does how do you get the spring cap to slide over it. Each time I slide the spring on the stem it pushes the ring out of the grove or is very difficult to get on so I'm not sure if the ring is still actually in the grove or just pushed down the stem. What is the purpose of this ring anyway?
It goes in the groove, but you have to compress the spring first. The seal sits in the cup of the retainer, right below the keepers. So compress the spring, install the seal,then install the retainers then release the spring.
RolngThun is right, Put the spring in place first (leave compressed), install o-ring seal in lower groove, then install keepers. Hint: Use positive type (umbrella style) seals as well, install them first over the guide boss, then do the above.
