Power Valve

Has anyone else had a power valve break off in the sleeve to the cylinder? I went to clean the power valves on my wife's 02 XCSP and pulled the power valve out and it was shorter than usual. It had broken off about a half inch below the base, with the other end being inside the sleeve to the cylinder about an inch or so, can't quite get any tools on it to pull it out.

It looks like the shaft just broke, it had to happen as I was pulling it out as it is so close to the opening so I don't think there will be any other damage.

Was it an 800? There were issues with the 800 valves breaking, they went to a titanium option which didn't work much better, then to stainless steel in the 800's. The failure is pretty common on 800's because there is a lack of cooling around the valve on the 800 cylinders. The valve gets hotter than on the other big blocks.

You may have to pull the head and see if the damaged part will pull into the cylinder for removal. Or sometimes working the part back and forth from both ends frees up what ever is sticking.

It is actually on a 500, I may be able to grab the piece and pull it out. If not, our mechanic at work has some extra work for him on Monday, LOL. I have included a pic of half of it.

Maybe try putting some super glue or 5 minute epoxy on a stick or rod and let touch the broken part, and dry, then see if you can gently pull it out without breaking the glue. Some of that stuff dries pretty strong, I have used this trick to pull slip pins out of holes,or broken slides out, maybe it will work for you.
