I am running 2 breather tanks, one for the valve cover and one for the block, they are both drained back to the same fitting on the block according to endyn instruction, the drain back dont work that great because of line size and angle of drain, plus its draining back to pressure.

now the question: has anyone tapped the plug that goes into the spot where the black box was and use it for drain back? I think this would be a great idea. maybe golden eagle or z10 could start offering these with a bung or fitting on them. I am gonna buy a extra z10 plug and try this.
what you guys think about this idea? if there is a better spot to drainback let me know, thanks

 

?

 

I've also considered draining from the catch can back to the pan , similar to the turbo drain line. I dont know why people dont try this.

 

the oil pan would be a great idea, if I did not have my breather cans mounted on the firewall I would use the extra bung thats on my moroso oil pan, I have 2 return bungs on the front of my oil pan. and one on the back which seems too low, if this z10 freeze plug idea fails I will get 2 extra bung welded to the back of my oil pan for the,
or maybe I should just jump to getting the oil pan bungs done instead.
they are both great ideas
