Phillip Robinson Posted October 16, 2020 Share Posted October 16, 2020 Should i use grease on the head gasket, or Hylomar spray. This is a 1939 prefect side valve motor. The new gasket is a copper composite, copper either side. Any thoughts? Link to comment Share on other sites More sharing options...
Oldtech Posted October 26, 2020 Share Posted October 26, 2020 Spray copper sealer or aircraft gasket sealer are my favorites. Link to comment Share on other sites More sharing options...

Phillip Robinson Posted January 11, 2021 Author Share Posted January 11, 2021 Fitted dry. Seems ok, but will have to replace camshaft, so I might be able to see if head gasket sealed or not, when I pull it apart. Thanks . Link to comment Share on other sites More sharing options...
