Dear Vintage - Opel friends,
I'm pleased to be able to offer you the following article:
1 exhaust sealing ring, Opel 4- & 6-cylinder cih
This inconspicuous sealing ring acts as the valve stem seal for the exhaust valve in older cih engines. Make sure you moniter it, otherwise it will smoke :-) - for the newer engines, for instance in the Omega A, there are other seals, so please take notice.
