Thanks Bill,
I will the for sure order the insertion tool for the ceramic seal and follow the HMM and the SL to every point.
Assuming the gear, impellershaft etc can be pressed out with som basic DIY press tools. I have a lathe in my workshop, so I can make some special tools.
Unfortunatly, I have to take the engine out from the fuselage. I dont want to struggle into the summer season with a worse leak.
