When testing last week, we got back to the dock to find oil everywhere. It came out of the breathers. I have Eickert valve covers and those crome filter breathers. I was told big HP motors need differant type breathers or a "puke tank style breather" (what ever that is?). What is the best breather for me to use. Another problem I never encountered with my 500 EFI'S!!

You have these covers?

Hi, Yes and those breathers

You need to weld extensions on those breathers with aluminum tubes about 8 inches tall and put fuel cell foam in the tubes so the oil doesnt come out the breathers.
