What have you done today with your Austin Seven

Early valve covers are also a different shape. They don’t have the rebate for the rubber gasket strip. Instead a flat cork gasket was used.

Your later cover would provide a better seal (using rubber) and I’ve used a later cover adapted by extending the holes on my special. Others may throw their hands up in horror at this modification or point out the downside of doing this.

Cheers

Good plan. Austin obviously changed the plate for a reason and the reason was that the earlier plate didn't seal very well. Only downside is that an early block doesn't have a top "lip" to seal against, not that much oil will come out at the top.

You can also get a silicon seal for the later plate.
