If you’re putting the cylinders at TDC(or valve overlap) don’t waste your time with compressed air. As long as you can tighten the valve spring up enough to compensate for the valve falling slightly just let it rest on the top of the piston.

Just to confirm you don't need air to complete this task? As long as the spring compresses enough to compensate for the valve dropping slightly until hitting the top of the piston?

What other tips should be considered while doing valve seal replacements?

Is it recommended or necessary to replace the springs while each one is off?

Do the umbrella seals slide off and then replace by just sliding back on? Any special tools needed for installation?

This is an interesting topic. Thanks in advance for the replies.

Bill, please keep us posted on how your removal and replacement is going.

Thanks,
