Can an effective seal simply be made from sheet cork gasket material of the same thickness?

If you work on any larger two or three cylinder motors, the air box cover gasket will come stamped out of a sheet of the correct material and the extra material is perfect for these six horse seals. drifterUS Member - 1 YearReplies: 116Topics: 80 September 18, 2019 at 4:26 pm #183600 Thank you gentlemen.
