[Chevelle-list] Valve Seal Replacement ?

[Dan Anderson]

I like to adjust the valves with the motor warm and running.  Back each one off, one at a time, then tighten 1/4 turn past when they stop clattering.  An old valve cover with the top cut off comes in handy.  They used to sell clips that attached to the rockers and plugged the push rods to keep the mess down.  You can do each side in about a minute that way.

You don't need to bring each cylinder up.  The pressure from the hose is plenty to keep up.  Bring #1 up so it so it's on the firing position before you do anything and leave the engine rest there.  Makes it much easier to readjust the valves once you're done.  It's a pretty straightforward job.  Should take about an hour.  When you remove the rocker arms and have the tool in place, compress the spring, pull the keepers off, then release the spring.  Pull it off, pull old seal off, then slide the new seal on, reverse the procedure, and your done.  Just make sure you adjust the valves properly....there is a specific sequence.

   I am going to attempt to replace the valve seals on my 350 this weekend.  I've never messed with heads at all, but am thinking it can't be too difficult.     
 
  I have an air hose adapter to keep the valves in place and bought a valve spring compressing  tool at Pate last weekend.
 
  I'll bring each cylinder to TDC, apply air, and use the tool to compress the spring and remove retainer & keepers.
 
  I am assuming that the seals just slide over the valves.
 
  Is there anything more to it than that?    Any Gotchas?      Do I lubricate the seals before sliding over the valve stem?  Are the keepers easy to align when I reassemble?    I googled Valve seal replacement & didn't find much to help.  Anyone know of a web site with pictures?
Thanx
