Did you happen to find any hint of what is causing your side sealing proble=
ms?  You are just having all kinds of weird problems and I still think ther=
e is some deeper flaw.

Now I need to find the courage to start testing at higher power.

I replaced the 3 lb wastegate spring with the weakest one I have; a 1.5 lb =
