Yes Dave I can elaborate a little. Probably will have more to say later after I get my head out of ------ pressurization, avionics and other issues. Major problem and why the engine was making aluminum is that the cam shaft apparently should not have been used. It had been repaired with chrome on the journals and besides being badly pitted some of the chrome must have been peeling off and gouging the aluminum in the case where the camshaft rides. This item was sent out to a repair shop and was red tagged as not restorable due to the chrome treatment and both key ways being too beat up. I am told that chrome treatment of these camshafts is not acceptable. None of this information comes from my experience or knowledge base all has been passed on to me.

I put around 1.75 hours on it at high power full rich to break in the new engine that Barrett Performance folks sent me back a couple of months ago. > > Thanks to all who gave advice especially about oil coming out of the turbos. As it turns out, the issue must have been oil drifting around the system during overhaul and seeping out when static and when running at low power for a short while. Today the engine appeared to be almost bone dry after two flights and the belly of the airplane appears to be dry and clean also. I couldn't say that for the engine before I removed it for overhaul. > > There are still any issues to deal with.
