Thanks for the information. A new trick to add to my arsenal.
In my case the valve moved about 3/16 of an inch before hitting the piston. Then it took some good force to unseat the keepers. I didnt need anything to act as a spacer between the top of the piston and the valves. I could see how this might not work for non-interference engines.
My proceedure was as follows;
1. Remove all the spark plugs.
2. Remove all the rockers.
3. Rotate engine to TDC on the cylinder being done. Use a feeler wire in the spark plug hole to be sure of TDC.
4. Replace both seals.
5. Move to next cylinder as defined by the firing order.
6. Repeat step 3 thru 5 till done.
7. Replace as many rockers as possible.
8. Rotate the engine a little.
9. Repeat step 7 & 8 till done.
No danger of dropping a valve and easy to rotate the engine without sparkplugs.
I got too many cars!! Insurance eats me alive. Dave
