Re: Valve Stem Seals
Well, what you're sayin' is true. The process you describe uses the air injected into the cylinder to hold the valves closed. You're going to be taking off the valve springs to put on the new seals. Without the air in the cylinder the valves would fall into the cylinder. There is another way to do the job, without an air compressor. here's how.
1. Buy some soft 1/8" cotton rope.
2. Remove the spark plugs.
3. On Cylinder Number one find the start of the compression stroke.
4. Hand roatate the engine untill the pistion is about 3/4 the way up the cylinder.
5. Insert the rope into the cylinder's spark plug hole.
6. Stuff the rope in till you've got as much in as you can.
7. Gently hand rotate the engine until the pision has compressed the rope all the way against the valve faces.
8. Now the pistion is holding the valves in place, cushioned by the rope.
9. Remove the springs and repalce the seals.
10. Gently hand rotate the engine in reverse so you can remove the rope.
11. Remove the rope.
12. Repeat steps 4 - 11 for the other 7 cylinders.
