Re: Which Engine Oil?

I was told long ago to use non-detergent oil in an engine built before detergent oils became available when you are certain the engine has never been apart. The thinking behind this is that there may be lots of goo attached to the the sidewalls of the engine that might break free and clog up your oil pump screen/intake. After a thorough rebuild it is fine to use detergent oil.
I do not offer this as gospel truth however (refreshing for a change, isn't it?) and welcome other wisdom to the discussion.
