Hello
I have found the cause. in my head I temporarily replaced the cover with Plexiglas. The cause was too dense felt which I replaced. After replacing it with finer ones, the oil pressure has normalized. Everything you wrote is correct. It comes down to the balances between the head and engine oil pressure. The Eureka is mounted with a small pointer preload. Only driven 1.8 km so far. I feel my way slowly and get to know the M9A.
Best regards
