Dear Vintage - Opel friends,
I'm pleased to be able to offer you the following article:
cork rocker cover gasket 'GT-rocker cover', Opel 4-cylinder cih
This seal is the suitable version for the aluminium valve cap found in the Opel GT and also for the 'Steinmetz' & 'irmscher' aluminium caps.
It differs from the 'normal' seals due to its smaller holes for attaching the cap to the cylinder head. 'Normally' this seal has an opening diameter of over 8mm, this seal has ca. 7mm. This is a reproduction made of the so called 'rubber cork', a very modern cork - material, dream-worthy quality, but all the same a cork seal 'made by edelschmiede'.
