Hello!

At topic, does anyone know how deep the groove is from Mazda, and how deep it must be minimum to allow the seal to seat the way it should?

I measure different depth on several of my plates, some I know have been lapped, but it would be good to know go/nogo measurements.

Thanks for any replies!

Nobody knows? My many plates measure anything from 1.52-1.65mm.
