That will not work...on a BB..... it's not large enough..... especially if you are making any HP at all....
And the filter in the container will clogg up with
oil and stop passing air.....
We had too go to a 3" breather and run the back of the block and the bottom of the block to the tank.....
Plus a 1 1/2" breather on the Dry Sump tank....
Big motors need lot's of venting....
