I just drained my Mishimoto can. After 5000 miles of normal driving the oil (Pennzoil Ultra 5W-30) was 10mm deep. The catch can has maybe 3-4 times that capacity.
Oh, that's you in the comments. I overlooked your username.Yeah and I just responded to that. Again the barbs are plastic 5/16. Try tightening those hoses down enough to seal and you'll be replacing the intake and and valve cover. I fixed mine by replacing the hoses with the proper size. 9.5mm are 3/8 and i guarantee those barbs are not 3/8. Here is a pic of the current hose I'm using.
You'll need a foot of 5/16 hose and 2 barbs to adapt from 3/8 to 5/16. I also put a 5/16 check valve on the intake side. I just responded to the youtube comment and linked back to here. I don't appreciate the flat out lying from them and the reviewer about Honda hose barbs being 3/8. He damn sure didn't use factory hose clamps on the provided 3/8 hoses. I wouldn't use fuel line really, but it was already here. Fuel line outside diameter is a little larger than the factory hose and you really want those squeeze clamps too so you don't take a chance on snapping the plastic barbs on the intake or valve cover. Take your factory hose to O'reilly and match it up so you can use the factory clamps. And Collin deliberately replied on youtube without using my screen name so I wouldn't be notified. I used his in the my reply to make sure he knows I'm calling him out.
On the same catch can vid? Was your comment deleted? I was interested in this catch can but your concerns/observations are valid, so I am wanting to see the out come.
