H2AD/oil
Graham,
I am running an H2AD in my -4. I built the engine up myself, and have reconditioned cylinders on it. I did the first 50hrs with same oil you used,running 75% or higher throttle settings, and now run the 100 plus also. I have about 100hrs on it now, and it is using about 1/2 qt every 8-10 hrs. Like yourself, I never fill above 5 qts. I have heard all the recomendations for the valve stem seals also, but didnt put them on mine. Sounds like you have done all the right things, so I will be curious if you find a solution! Good luck.
