Thank you. I'm not thinking of new heads simply to clean up the splooge. Rather, I've been latching onto all excuses to justify spending all that loot on heads. In fact, my stump-pulling motor runs like a dream and definitely is fast enough to get me in trouble so I do not need heads -- but I want 'em. Meanwhile, I've a very slow lower rocker box gasket leak on the rear that I've been putting off until I make a decision on heads. Probably I should forget about the external breather until after I address the heads.

Heavy Breathers are the worst culprits because of the Venturi effect in the tube. I went from oil pooling in my heavy breather to externally venting and seeing nothing more than a damp hose.
Also I've never been a fan of high pressure springs in a system and engine that is designed for volume not pressure. But that's another story...

That's the ticket. Everyone uses a "T" this is incorrect and creates apposing force on the opposite line. A "T" is for vacuum this is very low pressure and the "Y" creates a scavenging effect. I used 3/8" fuel line and a Y fitting. I even used zip ties to hold everything together.

I have the se back plate . Just got regular automotive hose and plastic 90 degree and one 3 way connector. Similar to the dk kit for se. ended up costing a little less then there kit but diy and had extra parts left over. Ran hose to the ground upfront. Almost totally out of site and heat has not damaged hoses or caused it to pop off the se plate vent bolt.

fashioned a piece of tube to plug the space were the se hose had gone into the filter(hard to see),one end fanned out and poked a hole to go thru the vent bolt as extra precaution it wont get loose.The joints were universal so made sure i trimmed them down to really make it breath,and still fit good and snug on the hose.
With cover on you can hardly see anything and there is no rubbing (pic 2) by leaveing just enough slack.
