That seal was my downfall – I tried to squeeze the graphite seal into the baffles BUT my 2 baffles were the later model i.e. an 11D motor (my engine is a mixture from the factory). So I cracked the baffles.
Took me a while but I found one in Finland from a DS so have used those. And this model of baffle does not use the seal. It basically spins the oil out and back into the sump (in theory and it is working at the moment with no oil leaks).
So I am afraid I can’t help on this one.
