Regarding blow by on that side only, thinking this through more. Even if the valve guides or seals were seriously bad on that side only, wouldn't the pressure be relieved through the drain back holes? I didn't think of that until now.

The oil expelled was in the shape of a number of small droplets, if that helps any.
Oil blowing out the breathers is from piston ring blowby, nothing to do with guides.

All comes down to the engines' condition, who assembled it, and how well the heads drain.

Me personally, I run my breathers from the crankcase. The rocker covers are sealed, no blowby flows out the rocker covers, hence no airflow up through the cylinder head drains.

A leak down test is in order; but if your oil consumption is ok, a redesign of your breather system may be an easier solution.
