I had a similar problem on my 245. I'd cleaned out the PCV flame trap with carb cleaner, and made sure the hoses were clear. still leaking.

then replaced the oil filter gasket and the breather box below the flame trap. still leaked out the top.

recently simply replaced the flame trap with an all new one. and replaced the pcv hoses that had cracks at the ends.

it is now much better. I'm guessing one of the pcv hoses was leaking in enough to diminish the vacuum that should have been pulled, or the restriction from even my recently cleaned flame trap was enough to cause the problem.

If I were you, i'd replace the flametrap, and make sure the pcv hoses are in good condition. if that doesn't do it, then try replacing the breather box, or worrying about high blowby.
