  • Engine: Valve removal, 259

    After I removed the valve springs, the valves in one head slid right out. The other side, several valves, that portion of the valve above the keepers was very tight going through the very upper part of the valve guide hole. So much so, there are some scratches on the valve stem above the keepers. I wiped them clean before removal. Also, one valve stem had a couple little dings in the very upper stem. The dings don't look recent. Any thoughts about this?

    Thanks

    It sounds like loose Valve adjustment may have hammered them and Mushroomed the Tops of the Valves. If they are tight at the center of the Valves, they are bent.
    Always replace the Valve Guides, roll the Push Rods and Valves on a Flat surface like a Table Saw or Drill Press Table to check them.

      I often have to clean up the keeper grooves in the valve stems with a flat file to remove small burrs that prevent them from going through the guides.

        Yes. If they are badly mushroomed, take a file and dress the very top of the valve to remove bulged out part before pushing it thru guide.

            I mic'd the valve stems, and they are just slightly bulged above the keeper groove. I gently filed them, and now they slide through like the others do.

            Thanks again for the help.
